To reduce interface brittle compounds of brazed joints, laser-textured surface pattern was used instead of excessive active element to enhance the wetting behavior of brazing filler on Ti3SiC2 ceramic substrate. The cylindrical surface pattern was designed by theoretical calculation and examined by numerical simulation. The numerical simulation results showed that the cylindrical surface pattern can...
In order to reduce or even replace the use of Sn-Pb solder in electronics industry, the laser-textured surface microstructures were used to enhance the wetting behavior of lead free solder during soldering. According to wetting theory and Sn-Ag-Cu lead free solder performance, we calculated and designed four microcosmic structures with the similar shape and different sizes to control the wetting behavior...
It often produces a stronger cohesive force between high resistivity dust and polar plate in ESP, but cleaning and papping always have not been resolved. In order to reduce cohesive force between high resistivity dust and polar plate, the influence of coating on force conditions of dust is analyzed in this paper, through theoretical analysising and calculating the appropriate coating materials are...
