表面工程技术是一门边缘科学技术。其应用范围十分广泛,在近代科学和工业生产的实践中,更显示出这一新技术具有极其旺盛的生命力和巨大的经济技术意义。 物体表面的磨损和腐蚀是使物体失效和破坏的主要形式。机械零件的损坏形式,一般可分为两类;第一类为非正常损坏。当零件在受到拉伸、压缩、弯曲、扭转、剪切、冲击等外力作用时而引起开裂、折断,或发生超过允许范围的变形。产生这种形式损坏的原因是由于设计不合理,或加工制造质量不
Surface engineering technology is an edge science and technology. Its scope of application is very wide. In the practice of modern science and industrial production, this new technology has even shown its extremely strong vitality and enormous economic and technological significance. Object surface wear and corrosion is the main form of failure and destruction of objects. Mechanical parts of the damage form, generally can be divided into two categories; the first category of non-normal damage. When the parts in the tensile, compression, bending, twisting, shear, impact and other external force caused when cracking, breaking, or deformation occurs beyond the allowable range. The reason for this form of damage is due to improper design, or manufacturing quality is not
