In many respects the existing conventional plasma spraying torshes have reached thair technical and technological limits for further quality and cost advancement in plasma coating and plasma forming of near-to-net shape parts.
Plasma jet equipment was exhibited at the Belgrade International Technology Fair 2001. The same year inventor Miroljub Vilotijevic was awarded the gold medal Nikola Tesla by the Belgrade Association of Innovators and Authors of Technical Improvements for the original design of the plasma gun.
Plasma Jet 100 has the power of 100 kW. It is completely automated, PLC regulated and it is the only commercially available mobile setup with such power. The construction of the plasma gun enables the production of plasma jet with a more homogeneous temperature profile, with greater thrust and length of the ejected plasma, compared to equipment developed by other companies.
Such voluminous plasma jet of 100 kW enables good melting and acceleration of larger quantities of injected material than previously possible on some other commercial devices. High thrust of plasma jet produces higher rates of particle velocity, leading to very good adhesion to the surface.

Coating materials can be different types of metal alloys (hardness 150-800 HV), ceramic-metal composites (800-1000 HV) and ceramics (1200-2400 HV). In practice, different coatings resistant to various effects or a combination of them are required, in order to solve problems such as:
WEAR
EROSION & ABRASION
CORROSION
CHEMICAL RESISTANCE
ELECTRICAL CONDUCTIVITY & RESISTANCE
OXIDATION
THERMAL BARRIERS
