Characterization of supersonic low pressure plasma jets

Malko Gindrat

Low Pressure Plasma Spraying (LPPS) processes use a DC plasma jet expanding at low pressure for fast deposition of dense coatings in a controlled atmosphere. The LPPS technology is widely used industrially in particular in the aeronautics and medical indus ...

Plasma Spray-CVD: A New Thermal Spray Process to Produce Thin Films from Liquid or Gaseous Precursors

Christoph Hollenstein, Philippe Frédérique Bruno Guittienne, Malko Gindrat

New dedicated coating processes which are based on the well-known LPPS (TM) technology but operating at lower work pressure (100 Pa) are being actively developed. These hybrid technologies contribute to improve the efficiencies in the turbine industry such ...

Plasma Jet-Substrate Interaction in Low Pressure Plasma Spray-CVD Processes

Christoph Hollenstein, Philippe Frédérique Bruno Guittienne, Malko Gindrat

Conventional equipment for plasma spraying can be adapted for operation at low pressure so that PECVD-like processing can be performed. The plasma jet generated by the torch is characterized by a high convective velocity and a high gas temperature. The inf ...

Inclusion of aerodynamic non-equilibrium effects in supersonic plasma jet enthalpy probe measurements

Christoph Hollenstein, Malko Gindrat

Low pressure plasma spraying (LPPS) is a thermal spraying technique that has found a niche for low oxidation products. It uses a low pressure environment (i.e:, chamber pressure between 2 and 90 kPa) and yields supersonic plasma jets. The enthalpy probe te ...

Mechanisms of films and coatings formation from gaseous and liquid precursors with low pressure plasma spray equipment

Christoph Hollenstein, Philippe Frédérique Bruno Guittienne, Malko Gindrat

Plasma spraying is a well developed and widely used technology, successfully applied for ceramic and metal coatings in many fields of applications such as aeronautics, gas turbine, automotive or medical. The coatings obtained are usually intentionally poro ...
