The supplier selection of laser pointer

Cladding materials and ceramics research. The laser cladding materials most commonly used Ni-based materials, Co. based on Fe-based use. Navy Logistics Institute [21] studied 45 steel surface preparation of the Co-TiC-WC metal-ceramic composite layer, hardness and high wear resistance. Huazhong University of Science [22] in (A3), of Q235 steel surface preparation of the Fe-WC metal-ceramic composite layer, and the development of Cu-based alloy for laser cladding and SiCp composite powder [23]. On the one hand the excellent performance of both the Cu-based alloys; the other hand, through to join the SiCp, and improve the organization and improve the hardness and wear resistance of the coating. The supplier of the raw material of  green laser pointer  should be qualified by the authorized qualification department.
Proposed: thermal spray alloy powder laser cladding materials is likely to result in the pores and cracks studied the Fe-C-Si-B alloy powder obtained according to the organization of the Department of metastable crystalline, and its degree of refinement than the C-Si -B laser alloying greatly improved, and add a small amount of CaF2 can significantly improve the process performance of the cladding material. Addition of rare earth in the laser cladding materials is of concern to many researchers, the Chinese Academy of metal [25] quickly fused by laser treatment the surface of steel containing rare earth coating of RE in the amount of the steel surface and the performance on the steel surface impact. The results showed that: laser melting the rare earth rare earth-containing coating allows more to join the steel surface. The supplier selection of laser pointer     matters a lot for the production of the laser pointer.
CNB-Ti + RESiFe coating after laser treatment the surface of rare earth content of 0.35%, Ni-Cr-B-Si + RESiFe coating after laser treatment the surface of rare earth content of 5.5%. To join the surface of rare earth in the modified layer is distributed more evenly, there is no significant concentration gradient along the depth, the surface even. Rare earth ferrosilicon wear resistance, oxidation resistance of the steel surface have a more marked improvement. The laser cladding ceramic phase more work using carbide such as TiC [26] and WC [27]. Some studies using oxides, such as of Al2O3 and TiO2, and of SiO2 [18], etc.. Chinese Academy of metal corrosion of the boride ceramic phase [28]. It means the raw material of    green laser    can be accepted from the supplier.
Laser cladding process. The laser cladding process can be divided into two categories: one is the supply of added material before laser treatment; the other is to add material laser processing supply. The first category is mainly preset method using powder, you can use adhesive, flame spraying and plasma spraying; The second category is automatically sent to the powder method. Tianjin Institute of Textile to the development of successful large-area automatic coating system [29], the application of laser power 1 ~ 10kW, can be used for broadband coating, can also be directly used for focusing the narrowband coating. Single-channel a coating width of 10 ~ 35mm (adjustable), single-channel a coating thickness of 0.2 ~ 8mm (controlled), the powder feed rate of 0.5 ~ 200g/min (adjustable), send pink accuracy <2%. CR2 battery of     led flash light   can also be called CR15270 battery.
Laser melting amorphous. Tianjin Institute of Technology to discuss the formation mechanism of amorphous Fe-B alloys laser melting [30] proposed a simplified physical model of temperature distribution in the weld pool, the amorphous formation process, and tested 130μm ~ 200μm thickness of the amorphous layer. Because of the unique properties of metal amorphous preparation of a layer of amorphous laser melting technology in the local surface of the metal parts is clearly an attractive, many units are research and development efforts. Performance and applications of the laser cladding layer. Here will also introduce a kind of    green laser pointer   in the bottle shape.
