Therm Chip removal processes for improving theproperties of sprayed coatings containing manganese
In many cases, chip removal processes must be utilised for the post-processing of thermally sprayed coatings in order to set the desired surface roughness and dimensional accuracy. The research results published here are...
Introduction of a day effect estimator in order toimprove the prediction of particle properties in anHVOF spraying jet
Thermal spraying processes are influenced by a wide variety of controllable and non-controllable factors. Due to random disturbance variables, spraying results may be extremely different depending on the day. With the ai...
Comparison of fine (-10 +2 µm) and conventional(-45 +20 µm) WC-CoCr 86-10-4 feedstock powders:Influence of the HVOF spraying parameters on theparticle and coating properties
The composition, morphology, shape and size of the powder feedstock significantly influences the subsequent properties of every HVOF-sprayed coating. For example, the inherent porosity or grain size of the particles is d...
