Formation of Spherical Particles in Thermally-Sprayed Cobalt-Based Alloys and Development of a Volume Parameter Using Metallographic Methods

摘要

Thermal spraying can be used to deposit cobalt-based alloy coatings with thickness of ca. 1 mm. In order to achieve the desired properties, the flame-sprayed powder must maintain certain physical and geometric parameters, the mathematics of which are discussed. From these, one can deduce the parameters for deposition of cobalt-chromium alloys, cobalt-tungsten and cobalt-carbon.
