Thermal Spray Coatings, Wear Resistant

Metallizing Equipment Co has implemented Thermal Spray Coating Solutions into production in order to minimise the effects of mechanical wear and extend product life, and is further developing them to meet even more demanding wear applications. Wear is defined as the unwanted removal of material from a surface as a result of mechanical action. Mastering the wear process means controlling a complex set of system and process variables. For each type of wear, there is a corresponding specific wear mechanism. Applying coatings using thermal spray is an established industrial method for resurfacing metal parts. The process is characterised by simultaneously melting and transporting sprayed materials, usually metal or ceramics, onto parts. The spray material is propelled as fine molten droplets, which, upon striking the part, solidify and adhere by primarily mechanical and, in some cases, metallurgical interaction. Thermal spraying can be used to apply coatings to machine or structural parts to satisfy a number of requirements: Repair worn areas on parts damaged in service, restore dimension to mis-machined parts, and/or increase a part’s service life by optimising the physical surface properties. The primary advantages of thermal spraying include the range of chemically different materials that can be sprayed, a high coating deposition rate, which allows thick coatings to be applied economically, and spray equipment portability. Before designing the proper coating system, MEC evaluates several factors and considerations. Technical considerations are based on an understanding of the wear mechanism and environmental factors the engineering parts are exposed to. Cost considerations include the materials use, gun and process employed, and the normal life of the components before they need to be repaired. The combinations are many, but the solutions options are great, and offer impressive benefits.
