TLDR
In this article, a Ni-P-PTFE composite bath is used to make steel surface coated with PTFE, and the coating is also provided with an advantage of good attachment.
Abstract
The invention relates to a Ni-P-PTFE composite bath. Each liter Ni-P-PTFE composite bath comprises nickel sulfate in the range of 25g to 40g, sodium citrate in the range of 20g to 36g, sodium acetate in the range of 5g to 12g, sodium hypophosphite in the range of 15g to 40g, OP-10 in the range of 0.5g to 2g and N, N-Dimethyl Aminoacyl in the range of 0.4g to 0.6g dissolved in water, and also comprises Teflon emulsion in the range of 7g to 18g. NAK-80 steel is dipped in the formulation to make the steel surface coated a Ni-P-PTFE coating. More PTFE particles are deposited in the coating and the PTFE particles are distributed homogeneously. And the coating is also provided with an advantage of good attachment. Moreover, the PTFE particles in the bath are stable and not easy to settlement, and can be used repeatedly.
