As we all know, all the materials have certain their service life, ans will have to suffer different forms of damage or abrasive wear, directly or indirectly, resulting in failure problems. The main failure forms are corrosion, wear and fracture, and abrasive wear is one of the main reason to cause materials failure, it may result in the decrease of components, machinery and equipment service life, or even cause a serious accident and severely reduce labor productivity, which will not only cause enormous waste of social resources, but also cause enormous economic losses.

Especially in modern engineering structures, many components will have serious wear damage high temperature, high pressure, multi-phase flow conditions, as well as corrosion, fracture etc. Abrasive wear has caused great interest and consequently, study of the wear mechanism and wear technology has great significance to the development of the national economy.

Actions to be taken to protect directly abrasive wear is to have high abrasion resistant coatings welded on the metal surface. There are many kinds of overlay layer, and has obtained the widespread application in the metal protection technology. Method for manufacturing metal coatings are mainly hot dip coating, electroplating, plating, brush plating, electroless plating, coating, mechanical plating, thermal spray, high energy beam (laser beam, ion beam, electron beam) surface modification.

Zhangjiagang YaoYu Wear Resistant Materials Co.,Ltd produces chromium carbide overlay plate against high abrasive wear by open arc welding machine, main products are wear resistant steel plate, abrasion resistant steel pipe, chromium carbide overlay liner, etc. Full size overlay plate can be cut into different size and shapes parts, for making different wear resistant steel products, such as cement mixer, chute, bucket, wear resistant steel liner, wear resistant steel pipe, etc.
