一、前言采用烧结合金的机械零件,一般在零件中含有油是用来润滑和防锈的,通常要编入机械制造工艺中。在浸渗油或只是表面涂油而防锈能力不佳时,通常需要进行蒸气防锈处理或磷化处理,而且对于既要求防锈效力高,又要求表面美观的零件,还可以进行涂漆。有关涂漆以及涂漆设备,已有不少文献 I. INTRODUCTION Mechanical parts made of sintered alloy are generally used to lubricate and prevent rust in parts. They are usually incorporated into the mechanical manufacturing process. In the infiltration of oil or oil is only the surface and poor anti-rust ability, usually require steam anti-rust treatment or phosphating, but also for both high efficiency and also require the appearance of the surface of the beautiful, but also can be painted . There are a lot of literature on painting and painting equipment
