The heat-resistant steel after aluminized was treated by laser shock processing (LSP) with high power Nd:YAG laser, and then was tensile tested at 400 . The effects of the high °C -temperature behavior after LSP were analyzed from residual stress and fracture organization. The results showed that the yield strength and tensile strength of heat-resistant steel after aluminized were improved obvi...

The effect of the thermal history on microstructural changes in aluminized and Pt-aluminized Ni-based single-crystal superalloys was investigated. The superalloy substrates were first electropolished to get rid of the residual surface strain. Then, Pt was electrodeposited and vacuum annealing was conducted for some of the substrates, and aluminized and Pt-aluminized specimens were prepared usin...

Turbine blades must withstand severe loading conditions and damage can occur during operation due to heat, pressure, foreign objects hot gas corrosion, despite the protective coatings applied onto turbine blades. Instead of replacing damaged components, maintenance, repair overhaul are key extend total service life. Besides welding, by brazing is an established process in industry involves many...
