Emerging Applications at University of Michigan - 100HE® Axial Feed Liquid Precursor Plasma Spray

Share

The Department of Mechanical Engineering at the University of Michigan has developed a number of breakthrough coating applications for the medical and energy fields using the 100HE plasma spray torch in the axial injection mode. These coatings were developed using sprayed nano particles in liquid suspension, and have achieved superior results as compared to standard thermal spray processes.

Major Application Highlight's Include

  • Particle size control, phase control and deposition efficiency can be substantially improved by axial injection of liquid precursor
  • However, in a single cathode DC plasma configuration liquid precursor is usually fed externally
  • A wide variety of nano-structured coatings have been obtained by axial injection approach at the University of Michigan
  • The deposition efficiency is much higher compared to side injection under identical operational condition
  • Axial injection also enables co-deposition of nano-particle embedded composite coatings using liquid precursors and common powders used in plasma spraying
  • These coatings can be consistently produced due to the wide range of operational parameters in 100HE torch as well as the stable arc behavior inherent to the torch design
