chromium carbide overlay plate has found an increasingly wide applications in all industrial fields, such as cement industry, power plant, concrete machinery, mining machinery manufacturing, etc. It is complicated to evaluate wear resistance ability of chromium carbide overlay plate, and it is a common sense to test hardness of chromium carbide plate, usually we will believe the higher the hardness, the higher abrasion resistance it is. We have different ways to mark surface hardness of a chromium carbide plate, namely Rockwell hardness (HRC), Vickers hardness (HV) and Brinell hardness (HB), all of these are easily to make us confused, so the relevant departments are suggested to make a national standard for that as soon as possible which can make much easier for us.

Hardness can show wear resistance ability of chromium carbide overlay plate partially, but it is only one-sided and not scientific if we only have hardness as a standard, it is better if we can take the following several aspects into consideration to get a comprehensive analysis:

1.Macro Rockwell hardness (HRC)
2.Metallurgical structure analysis: show clearly the micro-structure of carbide type, quantity, shape, size, distribution,it is  an important basis for analysis the wear resistance performance of chromium carbide overlay plate
3.Micro hardness (HV): measurement of micro hardness value of matrix and carbides
4.Wear testing: wear test is presented as the actual working condition
