Embodiment Construction

[0029] In order to more clearly describe a hard surface alloy material proposed by the present invention, the preferred embodiments of the present invention will be described in detail below with reference to the drawings.

[0030] The invention provide a hard-faced alloy material consisting of at least one base phase structure and at least one reinforce phase structure, and that hard-faced alloy material has a specific hardness which is greater than HV500. Particularly, the hard surface alloy material of the present invention must contain more than four main metal elements, and the main metal elements are selected from the following groups: aluminum (Al), cobalt (Co), chromium (Cr), copper (Cu), iron (Fe), manganese (Mn), molybdenum (Mo), nickel (Ni), niobium (Nb), and niobium (Nb). In addition, the hard surface alloy material further contains at least one nonmetallic element selected from the following groups: boron (b), carbon (c), nitrogen (n), oxygen (o) and Silicon (si).

Abstract

The invention provides a hardfacing alloy material, which can be coated on the surface of a target workpiece through an appropriate hardfacing process according to the material, size and performance requirements of a target workpiece. For example, by using various heat sources, the hardfacing alloy material of the present invention can be heated to a molten or partially molten state, and then coated on the surface of the target workpiece, thereby forming a well-bonded protective coating In this way, the excellent characteristics of the hardfacing alloy material of the present invention can be utilized to achieve the functional role of protecting the target workpiece, thereby prolonging the service life of the target workpiece.

Description

Technical field [0001] The invention relates to the related technical field of alloy materials, in particular to a hard surface alloy material. technical background [0002] In order to prolong the service life of equipment or workpieces, surface treatment technology is usually used to modify the surface of equipment or workpieces, or a protective layer is coated on the surface. Hardfacing process is usually applied to a metal workpiece, such as thermal spray, meltallizing, build-upwelding, Snitering, etc., and a functional hard facing material is coated on the surface of the metal workpiece, so as to improve the physical or chemical properties of the metal workpiece surface, such as wear resistance, corrosion resistance or resistance. Therefore, the service life of the metal workpiece can be effectively prolonged by effectively reducing the surface abrasion or corrosion. [0003] Hard alloy materials usually include a base phase alloy, which is made of iron-based, cobalt-based o...
