Defect Analysis of Tungsten Contacts

Defect analysis of tungsten contacts is an important part to examine the microstructure. According to the standards and regulations related to tungsten contacts, and the material microstructure to check the quality of products is good or bad, that is, according to the distribution of its microstructure to largely determine the defect type and its size finally check whether they meet the requirements of the relevant standards of the product specification.

The defect types of tungsten contacts including unevenly distributed organization, porous holes, pores, bubbling, delaminating cracks, squeezing cracks, inclusions, purity of tungsten contacts material or the particle size and morphology of tungsten powder, etc.. There may be a problem of the production process, the reason is complex, and it should be comprehensively analyzed and resolved.

Microstructure analysis is one way to test the quality of metal materials, which adopt the principle of quantitative metallography.

Defect types and sizes of products materials is related to production processes and others, so, analyze the cause of the defect phenomenon can provide reference for improving product quality.
