Benefits of technology

The present invention provides a hardfacing alloy that can be applied to a surface of a workpiece through different surface treatment processes. The hardfacing material can be heated to a fully melted state or a partially melted state and coated onto the surface of any workpiece to form a protective layer or surface modification layer. This results in a workpiece with superior characteristics that exhibits outstanding functional performances and a long service time.

Problems solved by technology

It is worth noting that, development and applications of the hardfacing alloy are found to be limited due to the fact that the composition design of the hardfacing alloy usually uses Fe, Co, or Ni as a principal element for forming the base alloy structure.
As a result, workpieces coated with different surface modification layers made of various conventional hardfacing materials are unable to satisfy requirements of environments implemented with the workpieces.

Embodiment Construction

[0021]To more clearly describe a hardfacing material according to the present invention, embodiments of the present invention will be described in detail with reference to the attached drawings hereinafter.

[0022]Traditional hardfacing alloys often contain one kind of primary elemental composition; for example, Fe-based, Co-based or Ni-based hardfacing alloy containing with other additional elements such as Cr, V, and / or Mo for enhancing corrosion resistance and thermal stability thereof. Particularly, the present invention discloses a hardfacing material comprises at least four principal metal elements at least four principal metal elements and at least one non-metal element, wherein the principal metal elements and the at least one non-metal element form at least one base alloy structure and at least one precipitation-strengthened alloy structure of the hardfacing material. It needs to further explain that, at least four principal metal elements are selected from the group consisti...

Abstract

The present invention discloses a kind of hardfacing alloy, which can be applied onto a workpiece's surface by any one surface treatment process in accordance with material, dimensions, and required properties of the workpiece. For example, this novel hardfacing material can be heated to a fully melted state or a partially melted state by using different types of heat sources, such that the melted hardfacing material can be coated onto the surface of any one workpiece to form a protective layer or a surface modification layer. As a result, the workpiece having the surface coating layer with superior characteristics exhibits outstanding functional performances and has a long service time.

Description

BACKGROUND OF THE INVENTION1. Field of the Invention[0001]The present invention relates to the technology field of alloy materials, and more particularly to a hardfacing material.2. Description of the Prior Art[0002]Surface treatment or modification technologies are widely adopted for forming a coating layer onto the surface of a workpiece, so as to extend the workpiece's service time. Hardfacing process is one kind of surface modification technology and used for coating a hardfacing material onto a workpiece's surface by thermal spraying, meltallizing, build-up welding, or sintering. After covering the surface of the workpiece by the hardfacing material, mechanical characteristics like wear resistance, corrosion resistance and / or thermal resistance of the workpiece's surface are then improved, such that service time of the workpiece would be obviously extended.[0003]Conventional hardfacing material is commonly a Fe-based, Co-based or Ni-based alloy containing with other additional ...
