Splat Formation Mechanism in Thermal Spraying*
In order to understand the splat formation process of individual splat deposited by thermal spraying, commercially available Nickel powders with diameter of several tens micrometers were thermally sprayed onto mirror polished AISI304 substrate surface. The deposited splat shows transition phenomenon from splash type to disk one in flattening on collision onto substrate surface according to both...
متن کاملModeling of splat particle splashing data during thermal spraying with the Burr distribution
Splashing of splat particles is one of the most important phenomena in industrial processes such as thermal spray coating. The data relative to the degree of splashing of splats sprayed with a normal angle are commonly characterized by the Weibull distribution function. In this present study, an effort has been made to show that the Burr distribution is better than the Weibull distribution for ...
متن کاملModelling for Thermal Control of Vacuum Plasma Spraying
Vacuum plasma spraying (VPS) is an industrial technique used to coat substrates with a wide range of materials for numerous applications. Historically, vacuum plasma spraying processes have been open-loop processes with, at most, closed-loop control of the spray parameters. Such processes would benefit from closed-loop control as the issues of process repeatability and coating quality could be ...
متن کاملIn situ Particle Generation and Splat Formation During Solution Precursor Plasma Spraying of YttriaStabilized Zirconia Coatings
Thermal barrier coatings (TBCs) based on Yttria-stabilized Zirconia (YSZ) deposited by the solution precursor plasma spray (SPPS) technique have been claimed to exhibit superior durability compared to conventional plasma spraying and even electron-beam physical vapor deposition. This has been attributed to the interesting features, like vertical cracks, nanosized pores, and fine splats that are...
متن کاملBreaks in Thermal Spraying Processes
The detection of structural changes in time series from industrial processes monitoring is of great interest. We investigate the limits and possibilities of two recently developed methods, one for the off-line detection of changed volatilities [Wied et al., 2011] and one for the on-line detection of changes in the course of the time series [Borowski and Fried, 2011]. The investigation is carrie...
