Laser surface strengthening and remanufacturing process technology is a set of optical, mechanical and electrical, computer, material, physics, chemistry and so on the multi-discipline interdisciplinary high technology and new technology, because of its unique advantages such as no pollution, low energy consumption, easy to automatic control and quickly developed into an advanced surface processing technology.
After more than 20 years of progress, the technology with high power laser, equipment, intelligent control and materials technology constantly upgrade and improve, has been more and more used to the strengthening and remanufacturing of industrial parts.
the laser surface strengthening and remanufacturing processing technology classification and description
laser surface strengthening and remanufacturing processing technology can not change the metal parts surface metal components under the condition of improving mechanical properties on the surface of the parts, can also be part of metal parts wear or strain class homogeneous cladding to repair and restore the shape size and performance, can also for some key parts to add metal parts surface modification on alloy or ceramic material, greatly improving the parts corrosion corrosion resistance, abrasion resistance, high temperature fatigue resistance. Laser surface strengthening and remanufacturing processing technical features: no pollution, good controllability, small heat affected zone, less tissue defect, treatment effect is good, easy to realize automation. Widely used at home and abroad of laser surface strengthening and remanufacturing processing technology three main points: laser quenching, laser remanufacturing ( Cladding) And laser alloying. The characteristics of these three kinds of technology and simple introduction:
with high-energy laser as a heat source, the metal surface quick hot cold, instantaneous quenching process, with high hardness, and ultra-fine martensite structure, improve the surface hardness and wear resistance, and the surface compressive stress, improve the fatigue strength.
