Abstract: An electroless nickel plating bath comprising: i) a source of nickel ions; ii) an effective amount of thiourea; iii) an effective amount of saccharin; iv) a source of hypophosphite ions; v) one or more chelating agents; and vi) optionally, other additives and a method of using the same to provide a high phosphorus electroless nickel plating deposit on a substrate. The high phosphorus electroless nickel deposit is capable of passing an RCA nitric acid test, whereby the substrate with the high phosphorus nickel deposit thereon is immersed into concentrated nickel acid for 30 seconds and a deposit that does not turn black or grey is deemed to have passed the RCA nitric acid test.

Abstract: A method of producing a composite electroless nickel layer on a substrate is described. The method includes the steps of contacting the substrate with a composite electroless nickel plating bath and generating an electrostatic field in the electroless nickel plating bath. The electric field is generated by placing an anode in the electroless nickel plating bath and connecting the anode to a positive terminal of a DC rectifier, and connecting the substrate to a negative temiinal of the DC rectifier, and preferably inserting a capacitor into the circuit to prevent passage of current. An attractive force generated by the electrostatic field increases the attraction of the positively charged PTFE particles to the negatively charged substrate and drives the positively charged PTFE particles to the negatively charged substrate.
