Paper Abstract

It is reported that the fatigue intensity and fatigue life can be improved when the laser surface treatment is carried out on the test specimen made with class I blade material (1Cr11Ni2W2MoV stainless steel) of WP-6A engine compressor. By comparing with the tests, we can conclude that the fatigue life of the treated specimen is 2.13 to 4.01 times as long as that of the untreated, and that when the power densities of the laser are 8578 W/cm2 and 9446 W/cm2, the fatigue limits of the specimens have increased by 19% and 41%, respectively, and we find the relation between the multiplication value of fatigue life k and stress S.
