Methods for repairing workpieces using microplasma spray coating

摘要

A method for repairing a workpiece (92) using microplasma includes the steps of generating a microplasma stream (21) having a width of about 0.5 millimeters to about 5 millimeters; applying the microplasma stream (21) to a workpiece (92); and coating a portion of the workpiece (92) with the microplasma stream without masking the workpiece (92). One or more quantities of powdered materials (34) entrained in the microplasma stream (21) may be applied to the workpiece without masking the workpiece (92) after applying the first layer.
