AI Technical Summary

Technical Problem

The surface wear problem of existing metallurgical rolls leads to a short life cycle, and traditional coating processes are complex and costly, making it difficult to optimize coating thickness while ensuring coating performance.

Method used

The alloy groove cladding layer 1 and alloy groove cladding layer 2 are sinusoidal structures, circumferentially staggered, and anchoring nodes are set at the intersection nodes. Combined with shot peening and thread roughening treatment, the alloy working layer is formed by optimizing the material ratio and thermal spraying process. The bonding strength and performance are improved by using the anchoring structure and material ratio.

Benefits of technology

It significantly improves the bonding strength and wear resistance of the coating, extends the service life of the alloy roller, reduces production costs, and maintains excellent oxidation resistance and corrosion resistance at high temperatures.

Abstract

This invention discloses an anti-oxidation and wear-resistant composite coating for an alloy roller surface and its manufacturing process, comprising an alloy groove coating layer one, an alloy groove coating layer two, and an alloy working layer. Both alloy groove coating layer one and alloy groove coating layer two have sinusoidal structures, circumferentially staggered on the alloy roller surface. At least one set of intersection nodes is formed between adjacent alloy groove coating layers one and two, and anchoring nodes are provided at the intersection nodes. Alloy groove coating layers one and two are located inside the alloy working layer. This invention improves the interlayer bonding strength and reduces the thickness by improving the structure, materials, and process, while also enhancing impact resistance, thermal shock resistance, and corrosion resistance to a certain extent, and maintaining high hardness at high temperatures.
