Abstract

Having achieved significant results in an experiment involving ionic implementation by immersion in plasma (IIIP), the use of this method is now being tested in some companies in the State. Ionic implementation (II) is a method of surface treatment with great impact in the new materials field and has been used in some state-of-the-art companies. The main factor restricting this process in more generalized industrial applications, however, is the nature of its line-of-sight implanting, which makes it different or impossible to engage in three-dimensional treatment of geometrically complex parts at low cost. In turn, ionic implementation through immersion in plasma (IIIP) has been opening up new frontiers and opportunities for industrial application. This processing takes advantage of implanting without line-of-sight and enables it to be independent of the area to be treated. In the first stage, development of part of the HIP (INPE/Metrolab) equipment in respect of the high-performance plasma source, was sought by using a highly efficient vacuum system and source of glow discharge with controlled potential. In the second, a new vacuum chamber will be built and integrated into the system with a high-voltage pulsar with a high repetition rate and other appropriate equipment. (AU)
