Abstract
The ultrasonic impact cladding (UIC) of steel surface using titanium alloy pins is comparatively studied. The cross-sectional appearance, roughness, hardness, and corrosion properties of EQ70 high-strength low-alloy steel specimens after UIC were compared to those after ultrasonic impact treatment (UIT) with steel pins. And the effects of substrate strength and pin diameter on the UIC layer were investigated. Results show that the specimens treated by the UIC have lower roughness and better corrosion resistance than the UIT-treated specimen. The hardness of the pin, as well as the hardness and strength of the treated material, has a decisive effect on the thickness and element content of the cladding layer. The prerequisite for generating a cladding layer on the steel surface with the UIC is that fragments should be produced from the pin under the impact.
