PT-MAT™ Co-MET PTA is a cobalt based metal powder used for corrosion resistant coatings. the weld overlay exhibit high tensile strength with high ductility and excellent corrosion resistance in a wide range of temperatures.
PT-MAT™ Co-MET PTA is easy to weld with a good resistance to cracking and can be applied in multi layers.
PT-MAT™ Co-MET PTA is applied through plasma powder surfacing or laser cladding on low alloy to high alloy steel. Typical applications are equipment subject to corrosion, cavitations-erosion combined with slurry erosion and impact.
