补充资料：有机覆层:有机覆层
在基体材料表面覆以有机材料的材料保护层。在机械製造中﹐有机覆层的绝大部分是涂装层﹐或称油漆层。此外﹐也有用橡胶或塑料作为覆层的。需要抗酸﹑硷和抗腐蚀性气体和液体的钢铁件﹐常用厚约 3毫米的橡胶(如氯丁橡胶)或塑料(如氯化亚乙烯共聚物)黏在表面﹐可长期保护基体不受腐蚀。这种覆层主要用在大型抗蚀容器或排气系统中。埋在土壤中的金属构件﹐常以聚乙烯带包裹保护。在喷鉬或喷不锈钢的表面上涂覆聚四氟乙烯﹐在150℃温度下摩擦係数很低﹐磨损轻微﹐适於製造低载荷和要求高度清洁的滑动轴承﹐或用在食品﹑精细包装和纺织机械上。各国的Du﹑Dx轴承都是以塑料与金属复合製成的。通过静电喷涂将环氧树脂﹑氯化聚醚﹑聚四氟乙烯以及聚氯乙烯等塑料粉末涂覆在金属表面﹐可获多种抗化学腐蚀性极好的覆层﹐可用於输水﹑污水处理和海洋平台的设备上。有机覆层在辉光放电情况下﹐有机单体可以聚合成无针孔的有机膜﹐用作电容器的介质层。
