Corrosion Testing
Product Application: Corrosion testing is a material test that detects chemical or physical (or mechanical)-chemical damage processes that occur to metals or other materials as a result of their interaction with the environment.
Product Shapes: Salt Spray Test, Pitting, Crevice Corrosion, Intergranular Corrosion, Stress Corrosion.
Introduction:
Corrosion test is an important means to grasp the characteristics of the corrosion system composed of materials and environment, to understand the corrosion mechanism, and then control the corrosion process.
Corrosion test function: In the process of equipment operation, the use of corrosion inhibitors can slow down the corrosion of the equipment, but whether the corrosion agent is suitable for the equipment itself needs to be understood through experiments. According to the results of the experiment, the type or proportion of corrosion agent can be adjusted to detect problems in time and eliminate the occurrence of major accidents.
Non-destructive Testing
Application: Non-destructive testing is a test method that examines the surface and internal quality of an inspected part without damaging the workpiece or raw material in working condition.
Product Shape: X-ray flaw detection, ultrasonic flaw detection, magnetic particle flaw detection, eddy current flaw detection, γ-ray flaw detection, penetration flaw detection (fluorescence flaw detection, color flaw detection) and so on.
Introduction:
NDT can be used to detect defects within and on the surface of materials or workpieces, to measure geometric features and dimensions of workpieces, and to determine the internal composition, structure, physical properties and condition of materials or workpieces.
NDT can be applied to product design, material selection, processing and manufacturing, finished product inspection, in-service inspection (repair), etc., and can play an optimal role in quality control and cost reduction.NDT also helps to ensure the safe operation and/or effective use of products.
By detecting internal defects in a product, it improves the product in the following ways: 1. Improving the manufacturing process; 2. Reducing manufacturing costs; 3. Improving the reliability of the product; 4. Ensuring the safe operation of the equipment.
Scope of non-destructive testing: 1. Inspection of weld surface defects. Inspection of weld surface cracks, non-fusion, leakage and other welding quality. 2. Cavity inspection. Check the surface cracks, spalling, drawing, scratches, pits. Through NDT, the defects inside and on the surface of materials or workpieces can be found, the geometric features and dimensions of the workpieces can be measured, as well as the internal composition, and the structure, physical properties and state of the materials or workpieces can be determined.

Scope of non-destructive testing: 1. Inspection of weld surface defects. Check the weld surface for cracks, failure to penetrate, leakage of welding and other welding quality. 2. Cavity inspection. Check the surface for cracks, spalling, drawing, scratches, pits, bruises, spots, corrosion and other defects.3. Condition inspection. When certain products (e.g. worm gear pumps, engines, etc.) are working, endoscopic inspection is carried out according to the items specified in the technical requirements.4. Assembly inspection. After the completion of a certain process, check whether the assembly position of each component meets the requirements of drawings or technical conditions; whether there are assembly defects.5. Excessive inspection. Check whether there are residual chips, foreign objects and other excesses in the product cavity.
Metallographic Analysis
Application: It mainly adopts the principle of quantitative metallography to determine the three-dimensional spatial morphology of alloy organization by using the measurement and calculation of the metallographic organization of two-dimensional metallographic specimens, so as to establish the quantitative relationship between alloys. Composition, structure and properties.
Product shape: Grain size, inclusions, decarburization layer, band segregation, high magnification organization, low magnification organization analysis, etc.
Introduction:
Sampling - Specimen Setting - Rough Grinding - Fine Grinding - Polishing - Etching - Observation
Step 1: Determine the sampling location and interception method Select the sampling location and inspection surface. In this process, the characteristics of the sample and processing technology should be considered comprehensively, and the selected part must be representative.
Step 2: Setting. If the size of the sample is too small or the shape is irregular, it needs to be mounted or clamped.
Step 3: Rough grinding of the sample. The purpose of rough grinding is to flatten the specimen and grind it to a suitable shape. General steel is usually rough ground on a grinder, while softer materials can be flattened with a file.
Step 4: Sample fine grinding. The purpose of fine grinding is to remove deeper scratches left by rough grinding in preparation for polishing. For general material grinding methods, there are two types of manual and mechanical grinding.
Step 5: Sample polishing. The purpose of polishing is to remove the fine abrasive marks left by polishing and become a clear mirror without marks. Generally divided into mechanical polishing, chemical polishing, electrolytic polishing, the most commonly used is mechanical polishing.
Step 6: Corrosion of the specimen. In order to observe the microstructure of the polished sample under the microscope, it is necessary to carry out metallographic corrosion. There are many methods of corrosion, mainly chemical corrosion, electrolytic corrosion, constant potential corrosion, the most commonly used is chemical corrosion.
Failure Analysis
Application: Failure analysis is generally based on failure modes and phenomena, through the analysis and verification, simulating the phenomenon of repeated failures, finding out the causes of failures, and digging out the failure mechanism.
Product Shape: Wear Failure Analysis, Deformation Failure Analysis, Corrosion Failure Analysis, Rust Failure Analysis, Fracture Failure Analysis, etc.
Introduction:
Failure according to its engineering significance can be divided into temporary failure and permanent failure, sudden failure and progressive failure, according to the economic point of view can be divided into normal wear and tear failure, intrinsic defect failure, misuse failure and overload failure. There are many types and states of products, and the form of failure varies greatly. Therefore, it is difficult to specify a unified model for failure analysis. Failure analysis can be divided into whole machine failure analysis and component failure analysis. Failure analysis can also be performed according to the stage of product development, failure occasions, and the purpose of analysis. The work process of failure analysis is usually divided into clarifying requirements, investigating, analyzing failure mechanisms and proposing countermeasures. The core of failure analysis is to analyze and reveal the failure mechanism.
The significance of failure analysis:
1. To reduce and prevent the recurrence of similar mechanical parts failure, to ensure product quality, improve product competitiveness.
2. Analyze the causes of mechanical parts failure, for the accident responsibility, criminal investigation, liability determination, insurance business, product quality standards revision, etc. to provide scientific basis.
3. For enterprise technology development and technological transformation to provide information, increase the product quality, so as to obtain greater technological content. Technical content, so as to obtain greater economic benefits.
Sample Processing
Application: Raw materials are processed into processed samples. The method of processing depends on the purpose of the sample. In order to ensure that the samples are representative, each operation must be carried out strictly and accurately during processing.
