... brittle and prone to spalling than iron boride layers. Boriding of nickel-base superalloys is typically performed with very thin boride layer depths (5 to 15 μm, or 0.2 to 0.6 mil), because thicker boride layers are more prone to spalling. Boriding of titanium and its alloys has been performed using gas...
