Information

Under normal circumstances, the laser optical cladding technology can be divided into two types according to the powder feeding process, mainly including the powder preset method and the synchronous powder feeding method. The process effects of these two laser cladding technologies are very similar. Among them, the synchronous powder feeding method is easy to realize automatic control, the laser energy absorption rate is high, and there are no internal pores, especially the cladding of cermets. Significantly improve the crack resistance of the cladding layer, so that the hard ceramic phase can be evenly distributed in the cladding layer.

1、Laser cladding technology has a fast cooling rate, up to 106K/s, which is a rapid solidification process, and it is easy to obtain a fine-grained structure or produce new phases that cannot be obtained in an equilibrium state, such as unstable phase and amorphous state;


2、The coating dilution rate of laser cladding technology is relatively low, generally less than 5%. It has a strong metallurgical bond or interface diffusion bond with the substrate. By adjusting the laser process parameters, a good coating with low dilution rate can be obtained, and the coating composition and dilution are controllable;


3. The heat input and distortion of laser cladding technology are small, especially when high-power density fast cladding is used, the deformation can be reduced to the assembly tolerance of the part;


4. When using laser cladding technology, there are almost no other restrictions on powder selection, especially for cladding high melting point alloys on the surface of low melting point metals;


5, The thickness of the cladding layer processed by laser cladding technology is wide, the thickness of single-pass powder feeding is 0.2~2.0mm, and it can be cladding in selected areas, with low material consumption and excellent cost performance;


6. In the process of laser cladding technology, its beam aiming can make inaccessible areas cladding. In addition, the laser cladding process is easy to automate and is especially suitable for common oilfields. Wear repair of damaged parts.
