摘要:
采用大气压等离子体喷涂和高速大气压等离子体喷涂技术制备Cu/W涂层,分别对该涂层断面的表面形貌、孔隙率、氧含量和结合强度进行测试分析.结果表明,高速大气压等离子体喷涂技术制备的Cu/W涂层在孔隙率和氧含量方面突显优势.采用高速大气压等离子体喷涂技术制备的Cu/W涂层孔隙率低于3%,且大部分孔径均小于1 μm,利用EDS测得的W涂层氧含量为w(O)=0.41%,该值与真空等离子体喷涂制备的W涂层含氧量接近.与真空等离子体喷涂技术相比,高速大气压等离子体喷涂制备W涂层技术的复杂性和制作成本显著降低,在工程应用中实用可行.
Abstract:
Tungsten (W) coatings were fabricated on copper (Cu) by atmospheric plasma spray (APS) and high-speed atmospheric plasma spray (HAPS) technique.The properties of the porosity,oxygen content,and the bonding strength were measured.The results obtained indicated that the HAPS-W coating shows beneficial properties particularly in terms of porosity and oxygen content.The porosities of the HAPS-W coatings are less than 3% and most of the pores were smaller than 1 μm.The oxygen content of the APS-W and HAPS-W coatings measured by EDS were w(O)=1.25% and w(O)=0.41% respectively.The results suggest that the HAPS-W coating shows better performance than that of the APS-W coating and some of the results of the HAPS-W coating has achieved the reported effect of vacuum plasma spray (VPS) W coating.Compared with VPS,the HAPS technique greatly reduces the complexity and cost of production.The HAPS-W technique provides a convenient and low cost way to obtain good-quality coatings,and it has great feasibility and practicality in engineering.
