A magnetron sputtering method for preparation of silver tin oxide composite coating

Our company have developed a magnetron sputtering method for preparation of silver tin oxide composite coating.Using magnetron sputtering were sputtering technology, based on the optimization of membrane-based gradient interface transition zone and sedimentary process parameter control and coordination, make the silver tin oxide composite coating can be achieved in the process of sedimentary basement and in combination with the solid coating, and can be released in a timely manner in the process of deposition coating stress, ensure the continuous growth of coating.The silver tin oxide coating prepared by this method has good contact resistance and surface roughness, and the nano-sized tin oxide is evenly distributed in the silver matrix, which can significantly improve the arc ablative resistance and service life compared with the traditional process.This invention method has less working procedure, high efficiency, green environment protection, simple operation of equipment, and good industrial application prospect.

A noble metal/oxide composite film with catalytic properties and a preparation method thereof

Our company successfully developed a kind of precious metal/oxide composite membrane with catalytic properties and its preparation method, the method is prepared by magnetron sputtering technique first preparation containing precious metals bivariate or multivariate pseudo alloy system, auxiliary atmosphere subsequent annealing treatment, preparation of precious metal/oxide composite membrane with catalytic properties.This process environmental friendly, simple, without the use of toxic and harmful chemical reagent, the basement has no special requirements, the catalytic performance by two steps, the compound film film adhesion strong, in the REDOX reaction, chemical power source, pollutant degradation, optoelectronic devices, and other fields have good application potential and prospects, for the industrial application of catalytic membrane provides a new thought of universal technology.
