Laser cladding machine is an emerging new technology that uses lasers and nano-materials to strengthen alloys in various parts.
Laser cladding, also known as laser remanufacturing, or laser repair, is a new surface modification technology.
By adding cladding material to the substrate’s surface, and using a high-energy-density laser beam to melt with the thin layer on the surface of the substrate. The coating forms a cladding layer.
The treatment can significantly increase the hardness and wear resistance of the surface and extend the parts’ service life.
The materials applied to laser cladding are relatively wide. It has been successfully developed in stainless steel, dies steel, malleable cast iron, gray cast iron, copper alloys, titanium alloys, aluminum alloys, and special surfaces. And has been used in a wide range of applications, such as the following: laser cladding of cobalt-based, nickel-based, iron-based, and other self-fusing alloy powders and ceramic phases.
Laser cladding of iron-based alloy powders is suitable for parts that require local abrasion resistance and are prone to deformation.
Nickel-based alloy powders are suitable for components requiring local wear resistance, heat resistance, corrosion resistance, and thermal fatigue resistance.
Cobalt-based alloy powder is suitable for parts requiring local wear resistance, heat resistance, corrosion resistance, and thermal fatigue resistance.
Ceramic coating has high strength, excellent thermal stability, and high chemical stability under high temperature, which is suitable for parts requiring wear resistance, corrosion resistance, and high temperature resistance. And oxidation resistance of the parts.
Laser cladding can be divided into two main categories according to the cladding material’s supply method, i.e., pre-set laser cladding and synchronous laser cladding.
Pre-set laser cladding is to place the cladding material on the substrate’s surface beforehand, and then use laser beam irradiation to scan and melt the cladding material. The content is added in the form of powder, wire, or sheet, with dust being the most common.
Simultaneous laser cladding is where the cladding material is fed directly into the laser beam so that both feeding and coating can be done simultaneously. The molten metal is also supplied primarily in the form of powder, but some also use wire or sheet for simultaneous feeding.
The primary process of pre-set laser cladding is pretreatment of substrate cladding surface — pre-set cladding material — preheating — pre-set cladding material — Laser melting – post heat treatment.
The primary process of synchronous laser cladding is the substrate cladding surface pretreatment — feeding laser melting— post-heat treatment.
