The ceramic coatings on the surface of some metals can improve the shortcomings of low microhardness, poorly corrosion and wear resistance, in the same time maintain the property of the metals.

金属及其合金表面进行陶瓷化可以改善金属基体的硬度低、耐磨耐蚀性差、可加工性差等不足，并且能保证原金属材料的使用性能。

Some product applications require properties of hardness and strength to resist penetration under high pressure and to provide maximum wear qualities only on the surface.

一些产品的用途决定其需要具有耐高压压溃的硬度和强度特性以及表面的耐磨性。
