前言现代照相机工业的发展对照相机内在质量的要求越来越高,根据国外照相机分析的结果,证明氮化工艺已广泛用于照相机零件,从而大大提高使用寿命。用氮化代替原有的工艺,可以降低原材料成本、简化工艺流程,提高零件耐磨性及表面抗大气腐蚀性能,特别对那些要求热处理变形小或者在装配时要矫形的零件,氮化更具有其独特的优点。由于照相机零件批量大而外形尺寸又很小,传
Preface The development of the modern camera industry has become more and more demanding on the inherent quality of the camera. According to the results of foreign camera analysis, it has been proved that the nitridation process has been widely used in the camera parts, thus greatly improving the service life. Nitride instead of the original process, can reduce the cost of raw materials, streamline the process and improve the wear resistance and surface anti-atmospheric corrosion properties, especially those who require heat treatment deformation or assembly of orthopedic parts, nitriding more Its unique advantages. Due to the large volume of camera parts and small size, pass
