Technical advantages of electroless nickel plating
①It does not contain cyanide, and no external direct current is required. It is a green and environmentally friendly product strongly advocated by the country.
②The thickness is controllable, and the thickness of the nickel plating layer is controlled according to the plating time, which can be used to repair scrap parts.
③High bonding strength, generally 350-400MPa, without peeling or falling off.
④Good lubricity, low friction coefficient, and the surface after nickel plating is basically flat.
⑤The profiling is good, and there will be no over-yin surface and excessive current density, and no grinding is required after treatment.
⑥The plating layer is nickel-phosphorus alloy, which is dense, firm, high hardness, good wear resistance, comparable to electroplated chromium, the hardness value is 550HV, and can reach 1200HV after heat treatment; the electroless nickel-phosphorus alloy layer is an amorphous coating, and it is resistant to The corrosion performance is particularly excellent, and the corrosion rate in various corrosive media is significantly lower than that of stainless steel and hard chromium layers.
⑦The plating layer is evenly distributed, unlike conventional electroplating that is affected by the current distribution. A very uniform coating can be obtained on parts with complex shapes and precise dimensions, including blind holes, deep holes, pipe fittings and the inner surface of the gap, without sharp corners or excessive thickening of edge protrusions, so there is no need for post-plating grinding.
