Mechanical parts Environmental surface treatment technology

A new generation of environmentally-friendly special alloy catalytic liquid surface, Chinese Academy of Sciences developed the national invention patents, environmental protection, to replace the traditional high energy consumption and high pollution plating technology products, which are: 1, non-toxic, tasteless, no waste emissions, the human body does not harm the environment does not constitute pollution, the environmental protection industry in 2013 national key projects to promote sustainable development. 2, a small investment in equipment, high efficiency, simple production process, easy to use and fast, does not require an external power supply. Can be directly placed in the plating catalyst solution soak for 10 to 50 minutes, it can be formed bright as a mirror surface, with the Golden effect, magically iron into a stainless steel, both beautiful and durable. 3, controllable thickness can be used to repair scrapped parts. Low cost per square meter cost about 10 to 25 yuan (according to the requirements of the plating, surface catalysis different thickness, costs fluctuate, such as purely decorative surface, costs only 6 yuan per square meter), only nickel-plated 1 / 2, 1/3 chrome plating, stainless steel 1/4. 4, and base metal parts combined with high strength, generally 350 ~ 400MPa, can not afford to skin, not falling, never rust. 5, the surface alloy layer of uniform density, regardless of the shape of complex surfaces sink hole, deep hole, the pipe wall, corner and other products, surface treatment can be carried out, no pitting, no porosity. 6, wear resistance, corrosion resistance, high surface hardness. 7, lubricating, low friction, non-stick is good, the surface of the rear catalytic treatment is an amorphous alloy, which is in a substantially flat state. 8, imitating nature better. No sophisticated technology current density is too large phenomenon, sharp edges or protruding portion is not particularly thick, post-processing is not required grinding. 9, other indicators performance coatings: microstructure: alloy, non-magnetic; mp: 860 ℃ -880 ℃; Density: 7.8 g / cm3; hardness: plated 550HV, after appropriate heat treatment up to 1200HV; binding force: combined strength on steel or aluminum above 400MPa, much higher than the plating nickel, chromium and the like; stress: stress within the steel is less than 7Pa; Gloss: L2 or 8-11 △ ?.
