Surface Spray Coating

With the aim of enhancing the anti-corrosion resistance strength of out bimetallic screw, our Co. had, in the year 1997, imported from Japan a spray coating equipment and after repeated testing, had discovered that this kind of coating treatment can produce a 1.0 to 4.00 mm coating thickness of WC/Co, CrC/NiCr anti-abrasion acd anti-corrosion resistance surface. .Coation Density : 98-99.8%. .Hardness Degree : Hv1100-1400° and above. .Adhesive Strength : 10000psi abd above. .Alloy Powder : WC, NiCr. .Adjustment in powder composition can be made to suit different kind of. material substrate Spray Coating Application : 1. For screws used in plastic injection moulding machines. 2. For surface hardness treatment of parts and accessoried used in the aero-space industries. 3. For srews an dfollers used in plastic extrusion moulding machine, cement manufaturing machine, printing press, paper-making machines. 4. For surface hardness treatmentof moulds and any metal parts afthe casting and ship-building industries. Coation Features : 1. Hingh degree of alloy density and hardness with low rate of porosity. 2. Even heation of alloy powder with low rate of residual stress. 3. Attaining effective spray coating. 4. High anti-abrasion and achieving even dis-tribution of hardness. 5. High anti-abrasion and anti-corrosion strength. 6. High adhesive strength with adjustable coation thickness.
