覆盖材料及其几个基本问题

覆盖材料已广泛涉及到许多工程领域，本文阐述了覆盖材料的隶属范围，基本概念，分类，基本功能，技术处理工艺，基体分类，与基体的作用种类，在基体上的形态以及相关的理论学科，提出了应从材料科学及交叉科学角度研究与应用覆盖材料，并指出了覆材料今后的研究发展方向。

Several Basic Matters of Covering Materials

The covering materials have widely touched upon many engineering fields.In the paper,the category,the basic concept and sorts,the basic functions,the process technologies,the forms on the base phase,the base phase classification and the interrelated theory of the covering materials are set forth.And the paper points out that the covering materials should be researched and used from the angle of the crossing subjects and the material science.And it pats forward the future developing direction of the covering materials.
