abrasion resistance and corrosion pump, the pump cylinder wall Amorphous tungsten alloy plating. Nickel-based alloys used in the spraying plunger, stainless steel or tungsten carbide alloys where all Dole said. Amorphous tungsten alloy plating is a new technology, has the following advantages : the coating hardness, abrasion resistance, have excellent corrosion resistance properties; Electroless plating both deep and good performance; utilization of materials, energy and water consumption is relatively low; no pollution, cleaner production; It can be used instead of chromium plating, production costs are slightly lower than chromium plating. Shengli Oilfield Katsushima mechanical oil pump barrel plating plant build a tungsten-based amorphous alloy electroplating production line abrasion resistance and corrosion properties of the tube wall coating pump better
