Boronization with carborane (C2B10H12) by ICRF has been applied routinely to the walls of HT-7 super-conducting tokamak for the reduction of impurity influx, especially carbon and oxygen. Significant suppression of me...
A new and safe boronization technique - ICRF boronization using carborane has been successfully developed on HT-7 superconducting tokamak. X-ray photoelectron spectroscopy (XPS) is used to analyze the properties of th...
The electrolytic coatings of boron and RE-boron on medium carbon steel are carried out in molten salt mix- tures respectively.The brittleness of both coatings has been measured by using sound-emission with the method ...
The TEM observation on the single-side thinned specimens was made of the nucleation and growth of boride during boronization for steel 20 and the influence of prior room temperature deformation.The results of X-ray di...
