Influence of heat treatment on the surface texture of an etched cast nickel-chromium base alloy: an evaluation by profilometric records.
Profilometric measurements were performed to test the electrochemically etched surface roughness of a Ni-Cr-Be alloy in the as-cast state and after porcelain firing simulation. A Student's t test at 5% risk leads to the conclusion that a heat-treated surface is significantly rougher than an as-cast surface after electrolytic etching. The exact cause of the increased roughness and how it improves metal-to-resin bonding must be evaluated by further research.
