Electro spark deposition of functional coatings

Electro spark deposition (ESD) provides surface repair and coating of structural steel and tool steels (after heat treatment) with layers of hard metals.

Coating of the part of the functional surface area of the cylindrical heat treated steel part with a WC-Co layer.

  

WC-Co coating layer on austenitic steel 17248  (DIN 1.4541, AISI 321) and line microanalysis of elements: Fe, Cr, W, C, Co, Ni, Ti.
