Abstract
A method of increasing the fatigue life of a metal part of a titanium alloy by subjecting it to the steps of abrasive cleaning and shot peening.
Claims8
A method of increasing the fatigue life of a part made of titanium alloy, which comprises subjecting the part to the steps of first abrasive cleaning and thereafter shot peening, said abrasive cleaning comprising blasting the surface of said part with particles having a diameter within the range of about 0.0024 to 0.0082 inches at a blast pressure within the range of about 10 to 50 p.s.i., said step of shot peening using a higher intensity and larger particle size than said step of abrasive cleaning.
The method of claim 5 also including the step of alkaline cleaning after the step of abrasive cleaning and before the step of shot-peening.
