China laser pointer will be safer for the human body and the environment

The main problems in laser melting management cladding layer surface is not flat, the follow-up machining a large amount of the junction of the alloy layer and the substrate is prone to defects such as cracks and holes, a great deal of difficulty to the practical application. At present, the laser processing system of fixed assets and the cost of maintaining relatively conventional surfacing and spray coating is more expensive, higher product costs which makes the laser-treated, laser cladding processing on a large scale in the oil field the practical application of one of the main reasons. In summary, laser cladding processing is a rapid solidification technique, which can produce the excellent organization and performance can not be obtained in the equilibrium. Substrate unlimited design coating composition according to the use of performance requirements. The spot matrix distribution of china laser pointer is also very attractive.
Performance of high-alloy steel surface can be prepared on the cheap steel and high strength and the bonding is unmatched by other surface treatment processes, particularly suitable in oilfield corrosion, friction and wear of the working conditions common vulnerability parts of the surface treatment and repair. Although there are still some problems in the application, but with the people of their theoretical and technical research gradually in-depth and tend to improve, I believe will in the near future in the industry dig out of its enormous potential and far-reaching impact. Laser alloying (Laser Surface Alloying, LSA) is a new method of local modification of metal surface processing, laser alloying process belongs to the scope of the material surface modification. The laser of china laser pointer contains 50mW green laser (532nm) and 100mW red laser (650nm).
It is the high-energy laser beam irradiation, the surface of a thin layer of the substrate material need to add alloying elements at the same time rapid melting, mixing and the formation of a thickness of 10 of l000 um of the surface melted layer, the melting layer during solidification to obtain the cooling rate of up to l05-108 ° C / s, equivalent to the cooling rate quench hardening technology can achieve, but also short due to the melting layer of liquid exists in the physical phenomenon of diffusion and surface tension effects, the surface only in the newspaper time (50us-2ms) form with the required depth and chemical composition of the surface alloying layer, rapid melting of the organization of non-equilibrium process allows alloying elements during solidification had reached a high saturation. Controlling interface of china laser pointer is the three-chip interface/XLR.
To form a common alloying method is not readily available compounds, and metastable phase and the new phase, but also in the surface alloys with special properties together elements consumption low Qian case. This alloy layer due to some performance above the substrate, so we reached the table while the purpose of the modification. The most prominent feature of the laser surface alloying process is only in the melting zone and a small impact area occurred changes in the composition, microstructure and properties, the thermal effect of the matrix can be reduced to a minimum, the deformation caused minimal. That it can meet the surface of the need to use, without sacrificing the overall characteristics of the structure. The alloying elements are completely dissolved in the surface. china laser pointer will be safer for the human body and the environment.
Obtained by thin-layer composition is very uniform, are not sensitive to the tendency to cracking and spalling. Its another distinguishing feature is the laser power density is high (104-108 W/cm2,). The melting depth is controlled by the laser power and exposure time to the metal surface of the substrate can form a depth of 0.01 ~ 2mm alloy layer. Due to the high cooling rate, so segregation is extremely small, and refine the grain size effect is remarkable. Ordinary surface laser alloying technology enables cheap useful wear, corrosion resistance, heat resistance and other properties, and can replace expensive overall alloy from the surface; and to improve the wear resistance of stainless steel, aluminum and titanium alloys. The green laser pointer is design based on the principle of safety and reliability.
