Title:
金属成品の瞬間熱処理法
Document Type and Number:
Japanese Patent JP5341971
Kind Code:
B2
Abstract:
Uniform nano-scale microstructures can be reliably formed on the surface layer of this metal product while still improving the surface roughness and make the surface layer robust enough not to disappear due to wear. The surface of the metal product is repeatedly subjected to instantaneous rapid heating and rapid cooling by intermittently ejecting onto the surface of the metal product shot with a mixture of three or more approximate but different particle sizes for a high ejection density, thereby forming uniform microstructures near the surface of the metal product and forming micro-diameter dimples in the metal surface.
