Plasma Transferred Arc System (PTA) produces a very high-quality deposit offering optimal protection with minimal dilution or deformation of the base material. It is a process that deposits very precise coatings of perfectly controlled alloys on mechanical parts that are subject to intense wear, significantly extending their service life.PTA technology is particularly effective in protection against corrosion, thermal shock, and abrasion. A wide range of overlay alloys is available for practically any part. Some alloys are very hard, others are softer with hard abrasion-resistant particles dispersed in a matrix. Certain alloys are made to rebuild a part to a required dimension while others are designed to be a final overlay that protects the work surface.
