Numerical Modelling of Gas-Dynamic Surface Coating

status: ongoing

The gas-dynamic spray coating is a technique in which surface coating is formed by treatment of a metallic substrate by a high-velocity impinging particle-laden jet. This process generates a thin layer with a complex nanocrystalline structure in the impingement zone. Optimization of spraying systems continues evolving from an empirical trial and error process to a model-based approach by virtue of the improving completeness and predictive capacity of mathematical models.
