ITSC 2017, Thermal Spray 2017: Proceedings from the International Thermal Spray Conference, 829-832, June 7–9, 2017,
... Abstract A new laser thermal spraying method has been developed and experimentally realized. The new method makes possible independent energy input to the powder stream and workpiece using conical laser beams and thus is more efficient than other methods. The new method offers environmental...

ITSC 2003, Thermal Spray 2003: Proceedings from the International Thermal Spray Conference, 1053-1061, May 5–8, 2003,
... Abstract In many empirical studies on the structure and properties of thermally sprayed coatings, a set of two predefined parameters (e.g. porosity and elastic modulus) is correlated over a narrow range of structural variation assuming a continuous correlation function. Such a data evaluation...
