＜Iron Based Spray Coating＞
Iron, nickel, and cobalt-based alloys are well known for their applications in high temperature. However, the iron-based alloys are less expensive than cobalt or nickel-based alloys. The cost-effective iron-based coatings have properties of high hardness, adhesive and abrasive wear resistance and high toughness. Their corrosive wear resistance is superior to coatings of ferritic and martensitic stainless steels. The iron-based coating can be used to be alternative to chromium plating with similar performance to extend component life and is comparable finishes after grinding.
Thermal sprayed iron-based coatings consist of some composition such as borocarbides will have higher hardness and salt spray corrosion resistance. The iron-based system consist of  significant nickel and molybdenum content have improved oxidation and corrosion resistance and can be used in high temperature applications involving sliding and abrasion wear such as exhaust valves on internal combustion engines.
General applications of iron-based alloy include hard bearing surfaces(bearing journals, fuel pump rotors, sleeves), resist abrasive grains(cylinder liners, pistons, pump plungers, hydraulic rams, crankshaft bearings), resist fretting with intended or non-intended motion(machine bed ways, wear rings, press fits, bearing seats), resist particle erosion at lower temperature(exhaust fans, hydroelectric valves), salvage and buildup on grindable steel (worn parts), resist oxidation at high temperature and the operation conditions with sliding and abrasive wear.
Plus Metal Tech (PMT) provides services of protective and functional coatings, such as wear-resistant, corrosion-resistant, erosion-resistant, conductive and insulative coatings. Our thermal coating service is fully customized. Process choices depend on customer’s demands and the chosen materials.
