Operating conditions and original problem
The power and mining example compares a plated valve shaft / stem surface covered for four months with a laser-clad surface.
Technical approach
DED deposits a Stellite protective layer on the worn functional surface.
Reported application result
The presentation gives a laser-clad service coverage of at least one year and reduced shutdown frequency.
