Main technical parameters and application range of surface treatment of mercury electroless nickel plating in Shenyang, Liaoning
Liaoning Shenyang Mercury Chemical Plating Factory Products--Mechanical parts electroless nickel-phosphorus alloy surface treatment processing coating has corrosion resistance, wear resistance, strong bonding, bright, uniform coating, no need for plating
Processing, application industry, no environmental pollution. Mainly used in steel, stainless steel, iron, cast iron, copper, titanium
, aluminum and other alloy materials. Can be petrochemical machinery, equipment and equipment; compressors, textile and chemical machinery, hydraulic valve bodies and hydraulic components, heat exchangers
, metallurgy, automotive, bellows, mechanical seals, air compressors, vacuum equipment, machine tools, military industry, plastic machinery,
Surface treatment of mechanical parts such as fans, pumps, valves, coal mining machinery, electronics and electric power.
First, the corrosion resistance is good. It is acid and alkali resistant and salt (except nitric acid). Many industries in many media
Parts made of ordinary steel are supplemented with electroless plating and can be substituted for stainless steel after plating. This not only reduces material costs, but also
Improve product quality and performance.
Second, good wear resistance. The hardness of the coating is high, and the plating hardness is generally HV436-509 (HRC45-50).
After heat treatment at 400 °C, the hardness is as high as HV660-1000 (HRC62-69), and the friction coefficient is small, thus resisting
Good wear and tear. Commonly used in oil machinery, such as sucker rods, sliding seal rods, pump pump cylinders, screw pump rotors, compressor piston rods, cylinder liners, coal mine hydraulic props, water pump spindles and other wear-resistant mechanical parts.
Third, the plating adhesion is high. Up to 300-400Mpa, 2-3 times of electroplated chrome, not easy to appear off the plating
Elephant.
Fourth, the coating thickness uniformity is good. Generally, the difference in plating thickness is 2-3 μm. Especially for grooves, threads, deep
Holes, complex internal cavities (such as hydraulic valve bodies, hydraulic valve blocks, etc.), inner surfaces and outer surfaces of longer pipelines (such as oil pump pump cylinders, oilfield tubing, heat exchanger heat exchanger bundles, etc.) protruding.
5. After plating, the dimensional tolerance can reach IT7-IT6 level, no need to machine.
Sixth, the component size error and wear can be precisely repaired.
Seven, the surface quality of the coating. The surface roughness of the plated parts is not lower than the surface roughness of the substrate. Post-plated part
The dimensional tolerances and geometric tolerances of the parts can meet the technical requirements at the same time.
Eight, brazing and conductivity, can be widely used in the electronics industry.
Nine, environmentally friendly electroless nickel plating is suitable for food and pharmaceutical industry machinery and equipment.
Ten, the working temperature can be between -80 ° C - + 700 ° C.
11. Steel, stainless steel, iron, cast iron, copper, titanium, aluminum and other alloy materials can be plated.
12. No environmental pollution. No harmful substances in the plating process; wastewater containing nickel ions is taken
Recycling and recycling, no emissions process, for green industrial technology.
Thirteen, the plating solution is commercialized. The commercial plating solution has stable quality, simple process, convenient operation and use cycle week.
Duration.
Due to these characteristics, the electroless nickel-phosphorus alloy technology has been adopted by more and more industries and enterprises, and the prospects are very
broad.
