Ti6A14V NiCrBSi + B4C Laser Cladding Process of coating

60 alloy coating exists (FeNi3, Ni), Fe3C, Ni] C, Ni31Sil2, Ni16Cr6Si7, Fe2C and (Fe, Ni) 23C6 and other alloy phase, they all have very high hardness. Different areas of the coating, the percentage of its constituent elements is different in Figure 4 (a) l corresponding to Figure 3 o'clock position, and its composition was 99.6% W +0.4% C,[link widoczny dla zalogowanych], carbon content very small. Mainly due to a large number of WC in the coating and the spray decomposition process of melting due to l7】. In Haystellite7 spray fluxing coating, and a variety of the South in the WC hard phase coexist in the coating, they are of high hardness,[link widoczny dla zalogowanych], can resist the piercing and external abrasive damage to the substrate, and can effectively some of the abrasive coating on the surface of the sliding friction to rolling with the chisel cut, reducing the role of abrasive wear of the coating. 3 Conclusions (1) Analysis of data from the test, the flame spray coating molten mass loss Hayste1.1ite7 0.0410g, N80 steel mass loss of 0.0899g, flame spray coating melting Haystellite7 excellent abrasive wear performance the N80 material. (2) in the Ni-based self-fluxing adding WC particles, which in the coating to the form of solid solution can improve the performance of Abrasive materials. (3) In the flame spray coating in the presence of small amounts of gold fusion pores and lack of fusion of the WC particles with the body, and part of the WC particles decomposed. (4) causing the overall wear resistance of coatings good reasons, because the alloying elements Ni and powder Cr, Si, C and other alloying elements combine into a higher hardness carbide phase in the wear test process, they are also anti- abrasive wear of the subject.
