Abstract

The invention provides an ice skate blade provided with an alloy coating and used for skating shoes. A matrix blade of the ice skate blade is subjected to heat treatment, different hardness degrees required by different parts of the ice skate blade are obtained, so that after being coated with the coating, the ice skate blade body has rigidity and toughness of resisting and transmitting ice push-off power, and a cutting edge can be wear-resistant enough and has surface roughness as small as possible. Besides, alloy coated powder of the skate blade alloy coating adopts a specific alloy element composition proportion, so that the hardness of the alloy coating is remarkably improved, and the ice skate blade has quite high wear resistance, good hardness and oxidation resistance.

Description

technical field [0001] The invention relates to the field of cutting tool materials, in particular to a skate blade for skates with an alloy coating. Background technique [0002] Ice skating is a sport that combines personal strength and technology with skates with skates as a tool. Ice skating is one of the main events of the Winter Olympic Games. The most important factor affecting the level of competition is the performance of the skates on the skates, in addition to the personal skills of the skaters. For example, the ability to transmit ice pedaling force, resistance to plastic deformation, resistance to brittle fracture and long-term wear resistance, etc. In the mechanical structure of ice skates, the physical characteristics and mechanical properties of the blade are one of the main factors that determine the quality of the ice blade, which involves the overall strength of the blade, the hardness of the blade, and the surface roughness of the ice-touching surface. ...
