研究了两种涂料在相同烧结工艺下对合金孔隙度的影响。经横切面金相分析显示,采用涂料A会使合金产生A02到A04的孔隙,采用涂料B烧结会使合金孔隙达A00。通过对两种涂料的成份、不同温度段的挥发物等进行分析,发现涂料A在液相烧结温度段... 研究了两种涂料在相同烧结工艺下对合金孔隙度的影响。经横切面金相分析显示,采用涂料A会使合金产生A02到A04的孔隙,采用涂料B烧结会使合金孔隙达A00。通过对两种涂料的成份、不同温度段的挥发物等进行分析,发现涂料A在液相烧结温度段的挥发物较多是使合金产生A04孔隙的原因;调整烧结工艺,可以减少涂料对合金性能的不利影响。 展开更多

It has been accomplished comparative survey of the structure, substructure and submicro porosity of coatings of fine metals with face-centered cubic lattice Au and Ag being condensed in both conditions of space flight... It has been accomplished comparative survey of the structure, substructure and submicro porosity of coatings of fine metals with face-centered cubic lattice Au and Ag being condensed in both conditions of space flights of orbital stations and earth-based conditions. Urgency of such surveys are concerned with the necessity of settling the issues of creation of the advanced technologies for developing and recovery of different coatings-thermostatic, protective, optical etc. in space-based conditions. 展开更多
