The technology of metal vapor vacuum arc on the other hand is the reaction of pure metallic ions in a gaseous state with special gas molecules in a reactor vessel followed by negative impulse bias attack. These two surface enhancement technologies are capable of creating treatment surface depths up to several hundred nanometers depth. This research postulates the utilization of metal vapor vacuum arc technology to effect enhancement of sodium glass surfaces while making use of titanium ions to speed the attack of oxygen molecules thereby implanting a photo catalyst formation on the glass surface. 　　Laboratory experiments have shown that after surface treatments are effected by metal vapor vacuum arc technologies then oxidation ability is from 15~20% when tested by argon based blue; testing by UV/VIS shows permeability is reduced by 40%, while at the same time germ levels are solidified into masses thereby enhancing germ resistance. Another aspect is pressure crack test shows photo-catalyst are implanted at depth of 150~200nm and so testing by GIXRD results in no findings. 　　Metal vapor vacuum arc ion implantation technology is a new “dry” process method of which optimized parameters include low temperature, coatless and pollution free, and so this is an environmentally friendly technology. This process of this research, namely photo catalyst implantation, obviously shows the power of dissolving organic elements while reaching a “clean” state; in addition, reduced permeability results in surface luster while at the same time germ levels are reduced. This method may be used on either car or building glass windows for assessment. I hope to do even further focused research in the future in the hope that resultant formations will be even better controlled.
