Abstract
A method of heat treating and coating a nickel base alloy containing chromium, titanium, aluminum, cobalt, molybdenum, tungsten, boron and carbon. The alloy is heated at a temperature of at least 2050.degree. F. to put most of the coarse gamma prime particles into solution; coated; treated at a temperature of at least 1600.degree. F. to lessen the sharp differential in chemistry between it and the coating at the interface thereof; treated within the temperature range of between 1500.degree. and 1800.degree. F. to precipitate fine gamma prime particles, to coarsen existing gamma prime particles and to precipitate discrete carbide particles; and treated at a temperature within the range of between 1300.degree. and 1500.degree. F. to precipitate additional fine gamma prime particles, and discrete carbide particles at grain boundaries.
