"High abrasion resistance, corrosion resistance, environmental protection type narfell tungsten alloy plating process technology project won second prize of national technology invention. Recently, the project leader Professor He Fengjiao, the victorious return from Beijing. According to the introduction, this technology to completely solve the problem of pollution of chromium plating, and let the drilling tool in the high temperature and high pressure and high corrosive kilometers underground work. At present, including CNOOC, including the oil giant to extend an olive branch, intended to cooperate to develop this technology.

The narfell electroplating process new electroplating method by Hunan University and is located in Wangcheng District of narfell Hunan Science and technology new materials jointly developed by, is considered to be the best alternative to chrome plating process. The results let the screw drill can be deep underground hundreds of meters or even kilometers of oil wells, in the high temperature and high pressure and strong acid and alkali environment for a long time. The use of domestic tungsten alloy plating process, less than 1/5 of the use of foreign materials.

The results have been obtained 8 patents, won the national machinery industry science and technology award, and won the national technological invention two, and so on. According to reports, with this technology, Hunan narfell technology new materials company is expected to achieve output of 3000000000 Yuan in 5 years.
