Tungsten carbide hole saws hardening treatment It is worth noting that high-speed flame spraying has developed rapidly, occupying about a quarter of the market and ranking second. The development trend and characteristics in recent years are: large-area long-term protection technology has been widely used, and those steel structural parts exposed to the outdoor atmosphere for a long time are sprayed with aluminum, zinc and their alloy coatings instead of traditional painting methods.
Tungsten carbide hole saw hardening treatment coating is mostly a single metal or alloy, such as titanium target, zinc, cadmium, gold or brass, bronze, etc.; there are also dispersion layers, such as nickel-silicon carbide, nickel-fluoride graphite and so on. There are also clad layers, such as copper-nickel-chromium layer on steel, silver-indium layer on steel, etc. In addition to iron-based cast iron, steel and stainless steel, there are non-ferrous metals, such as ABS plastic, polypropylene, polysulfone and phenolic plastic, as the base material of the hardening treatment of the tungsten carbide hole saw. However, the plastic must undergo special activation before plating. And sensitization treatment. Tungsten carbide hole saw hardening is the process of plating a thin layer of other metals or alloys on the surface of some metals by electrolysis. During electroplating, the plated metal is used as an anode, which is oxidized into cations and enters the electroplating solution; the metal product to be plated is used as a cathode, and the cations of the plated metal are reduced on the metal surface to form a plating layer.
The hardening treatment of tungsten carbide hole saw has good insulation and chemical stability, but the texture is fragile and the forming of large workpieces will be difficult. However, through thermal spray coating technology, a ceramic coating is prepared on the workpiece to replace rubber And resin inlay layer can still be successful.
