BAIJIAN - Third party testing organization
In materials science and engineering、 there are famous material four element diagrams、 namely composition/structure、 synthesis/processing、 properties、 and performance. Different element ratios constitute different types of alloy materials、 and different heat treatments endow the materials with different organizational structures. Combined with specific processing processes、 they meet the performance requirements in different environments. The four elements are interrelated and influence each other、 which leads to the detection of materials Classification of Metal TestingMaterial Analysis
One of the most commonly seen tests in the mechanical industry is the chemical composition analysis of materials. With the progress of modern metallurgical technology、 it further proves the importance of some specific elements.. The different types and ratios of elements directly determine whether the material can achieve the required performance through subsequent processing. Common analytical equipment includes inductively coupled plasma luminescence spectroscopy (ICP)、 direct reading spectrometer、 and manual chemical analysis Analysis of metal material coating
Main testing items: identification of metal coating material、 coating thickness、 coating composition analysis、 sample surface stain analysis、 zinc plating amount testing、 coating surface roughness testing、 coating adhesion testing、 etc.
Metallographic inspectionOrganizational determination performance.
. The internal organizational structure seen under a microscope is called microstructure or metallographic structure. The common metallographic structures of steel include ferrite、 austenite、 cementite、 pearlite、 etc. The metallographic examination of materials specifically includes the composition and distribution of various phases、 as well as related casting and welding defects. The commonly used Dongbiao testing and analysis equipment are stereomicroscopes and metallographic microscopes Mechanical propertiesThe mechanical properties of materials refer to the behavior patterns、 physical essence、 and evaluation methods of deformation、 damage、 and fracture under external loading or combined loading and environmental factors.. The common physical and chemical performance tests in the mechanical industry include tensile performance、 impact performance、 bending performance、 cloth/Luo/Wei hardness test、 wear resistance test、 and fatigue test Environmental simulation test
This section mainly evaluates the performance of raw materials and finished products exposed to corrosive environments.
. The equipment can undergo traditional tests or specialized corrosion tests. Evaluate product reactions based on potential lifespan、 appearance、 related stresses、 material interactions、 etc. by accelerating exposure cycles or simulating environmental conditions testing. Common tests include salt spray test、 cyclic test、 weather resistance test、 and so on Non destructive testing
Non destructive testing plays a crucial role in related fields、 ensuring the integrity of steel structures and mechanical components. Non destructive testing methods can detect many types of defects such as cracks、 incomplete welding、 porosity、 etc. Common inspection items include visual and optical inspection、 X-ray inspection、 magnetic particle testing、 ultrasonic testing、 and penetration testing
