abstract = "The major drive for PIII research in recent years has been the
widespread use of plasma-based ion implantation in industries
aiming at attaining high value-added components. After achieving
the domain of the complete basic PIII cycle, we started to pursue
the implementation of this process in various types of industrial
components. A DC glow discharge source with a controlled plasma
floating potential was used in a 100-l PIII system driven by a
30-kV peak voltage, 50 ms duration, up to 1.1 kHz pulse power
source, in order to process the components which were provided by
regional companies, spanning from machinery tools to prosthesis.
The industrial components were set-up in the PIII chamber as
received from the companies, after a simple cleaning procedure. In
this phase, only nitrogen implantation was performed. The required
processing times were typically from 60 to 120 min and the
components were treated either individually or in batches. Fast
steel drill bits, knife blades for wood cutting, tools for
odontological applications, molds made of fast steel, a prosthesis
made of Ti alloy, etc., have been three-dimensionally implanted
successfully. Next, improvements in the PIII ongoing system
included: a 10-kW pulser with up to 60 kV capability, turbo-pump,
refrigerated walls, auxiliary heating of the components, a larger
chamber and a magnetron sputtering source for hybrid treatments.",
