摘　　要：PVD涂层近年来在模具行业的应用越来越多,涂层时必须考虑使用条件、模具材料、热处理工艺等因素。根据多年涂层行业的工作经验,认为保证模具涂层后基体仍具有高的硬度至关重要,归纳了拉伸模具、剪切模具、铝合金压铸模具和汽车冷镦模具等涂层时应该注意的关键技术问题。Recently PVD coating is more and more used at mould trade,and it is noted that selection of coating must be combined to operation procedure,mould material and heat treatment process etc.After many years＇ work experience,author considers that it is important to ensure the plated mould has high hardness and states the problems from making coating on tensile mould,shearing mould,aluminium alloy die-casting mould and car chill mould.
