Electrochemical polarization measurement and neutral salt fog test were carried out to investigate the corrosion resistance of high-velocity-air-flame (HVAF) sprayed WC/17Co and WC/10Co4Cr coatings before and after sealing with silicon-fluorine resin on low alloyed 300M steel substrate.
通过电化学极化测试和中性盐雾试验,研究了300M低合金钢上空气助燃的超音速火焰喷涂(HVAF)WC/17Co、WC/10Co4Cr涂层及硅氟树脂封孔处理后的抗腐蚀性能,并和电镀硬铬(EHC)的性能进行对比。
In this paper,the effects of gold on the formation of fog centers were studied by adding silver halide solvents after the emulsions were fogged by thiourea dioxide and thiourea dioxide plus gold, respectively.
本文使用在灰化结束后加入卤化银溶剂的方法研究金在灰化过程中的作用,并交替应用金浴(Au~+)增强灰雾中心,再用氰化钠浴(CN~-)选择性地除去灰雾中心的金,研究金与灰雾中心的作用。
The locations of the fog centers preferably formed in the grain introduced by light are different from those introduced by reducing agents.
光灰化和还原剂灰化生成的灰雾中心的位置不同。
The probabilities of increasing signal to noise ratio and enhancing the quality of an imaging in fog with this experimental method are d.
