A protecting key is provided for this kind of green laser pointer .
The process parameters such as the protection of the gas type and flow rate, powder flow and powder feeding position, laser power, powder nozzle diameter, scanning speed and the defocus amount, preheat temperature, etc. have a significant effect on quality. Application examples. Application of laser cladding technology to deal with the mold surface can be either machined into billet manufacturing mold surface modification can also be the mold for the forming of a certain number of normal failure surface repair, the fact that, as long as the proper understanding of the laws of die wear in the life cycle of the mold surface protective treatment in a timely manner, we can extend the maximum life of the mold. green laser pointer has been becoming popular since they first appeared on the market.
green laser pointer are innovative, integrated with laser indicators
The application of laser cladding technology the key lies in the choice of coating materials, process method, the choice of process parameters. Cladding materials, including self-fluxing alloys, composites, ceramic materials, these materials have excellent wear resistance, corrosion resistance, and usually in powder form. Performance characteristics of various types of cladding materials, the following table. The laser cladding methods and processes: Alloy synchronization method using a specialized feeding system during laser cladding alloy materials sent directly to the laser active region, the substrate and the alloy at the same time the role of the laser melting, and then cooling crystallization of the cladding layer.To solve this typical problem, education industry has attached great importance on the close combination of teachers experience, habits and the modern teaching equipments including green laser pointer .
In order to ensure uniform distribution of optical power density within the laser spot, so that the shape of the powder flow and spot shape and size to match the strict control of powder flow and substrate, the laser beam among the relative position. General power density 103-108W/cm 2, the cladding process is completed within the 0.1-1s. After heat treatment furnace heat insulation, full after the furnace cooling to eliminate the residual stress of the cladding layer. Machining, machining, and check the quality of surface treatment.
