Polishing is necessary to meet surface finish requirements that can not be achieved by machining or grinding. Actually achievable surface finishes depend on the material and are defined on individual material-technical bulletins.
Polishing of sprayed metal requires no special skill as long as the operator has the experience and understanding that the material is not a solid piece of metal, but a thin veneer which is bonded to the base metal mechanically and not by fusion. Technically polishing refers to processes that use an abrasive that is glued to the work wheel. Due to this requisite experience, Teknokraftindo Asia offers a full turn-key thermal spray coating service which includes Finish Polishing.
