Nickel-Teflon coating machining process applied to screws and nuts

应用于螺钉螺母的镍-特氟龙涂层加工工艺

Abstract

本发明涉及涂层技术领域,特别是涉及一种应用于螺钉螺母的镍-特氟龙涂层加工工艺,将六水硫酸镍、次磷酸钠、聚四氟已烯乳液以及湿润剂进行配制作为电解液,使用该工艺处理得到的螺钉、螺母产品不仅耐磨性、防腐性好,而且具有可焊及可淬性,不对螺钉、螺母产品表面产生任何负面影响。
The invention relates to the technical field of coatings, in particular to a nickel-Teflon coating machining process applied to screws and nuts. Nickel sulfate hexahydrate, sodium hypophosphite, polytetrafluoroethylene emulsion and a wetting agent are prepared into electrolyte. Screw and nut products prepared by means of the production process are good in abrasion and corrosion resistance and have weldability and hardenability, and no adverse influence is produced on the screw and nut products.
