Influence of processing parameters and heat input level on the functional properties of atmospheric plasma sprayed Al2O3- 3TiO2 commercial coating

Popis výsledku v původním jazyce

This paper concerns the combined influence of spraying parameters and heat flux level during atmospheric plasma spraying process of commercial alumina-titania coating. One of the main industrial application of alumina-titania are wear and abrasion resistant protective thermally sprayed coatings. Commercial high throughput plasma torch with cascaded construction is used as the spraying equipment. Three sets of spraying parameters were used for the basic evaluation of their influence. Additionally, three levels of heat input during spraying process were added to some of those sets of parameters. Those heat input levels are called "cold", "hot" and "extra hot" depending on the relative amount of direct heat input and maximum achieved surface temperature. Comparison of surface hardness, microstructure and especially abrasion resistance is carried out. Results confirmed that for successful design of such ceramic coatings, appropriate and sufficient heat input during spraying process into the complex of layer-substrate is required.
