Our company is specialized in developing, producing all kinds of fence manufacturers, is a professional manufacturer of spray fence. Spray the outside of the fence means there is a layer of coating layer fence types. Spraying the thermal spraying such as a guardrail refers to finely dispersed metallic or non-metallic coating material, in a molten or semi-molten state, is deposited onto the substrate via the production of one kind of surface to form a sprayed deposit. Then sprayed layer characteristics are like? Coated substrate medium hardness, equivalent to the general hardness of quenched and tempered steel, but the coating matrix pervaded lot of hard particles such as Cr, C: and WC, its hardness is up 10480MP-1607OMPa. These hard particles on the cutting tool serious abrasive wear, so soon blunt razor. Combined with the part matrix coating layer spraying fence basically mechanical bond, the bond strength is low, generally only 20-30MPa. If processed cutting force is too large, there may come off the coating, thus, it is should first be noted that an important feature caused. Reduce the tensile strength of the coating, similar to the gray cast iron strength. Due to the porous coating sandblasting machine organization, a certain porosity, because nickel chromium coatings are more low thermal conductivity and thus the coating, cutting heat came from the hard parts, chips, calories and more concentrated at the tip, the thermal effect of exacerbating cutting edge wear.
