Title

Computer model to simulate the random behaviour of particles in a thermal-spray jet

Output type: Journal article
Journal title: Surface and Coatings Technology
Month/year of publication: December 2006

Other relevant details: This paper adopts a probability approach using the Monte-Carlo method to simulate the behaviour of the particles in the thermal spray jet. The model identifies the critical process parameters and particle properties that govern the quality of the coating. The paper also develops process charts as a more user-friendly basis for industrial quality control. The variability in coating properties due to the random element in thermal spraying is a serious problem and this paper makes an important contribution to both understanding and controlling the properties of high-performance coatings.

Title Influence of composition and process parameters on the thermal spray deposition of UHMWPE coatings
Output type: Journal article
Journal title: Journal of Materials Science
Month/year of publication: January 2005
Pagination: 77-85
Volume: 40
ISSN: 0022-2461

Other relevant details: Ultra-high molecular weight polyethylene (UHMWPE)has remarkable properties for a polymer but cannot be thermally sprayed to produce coatings. This paper applies a computational model and experimental trials to provide the conditions under which UHMWPE-based coatings can be successfully deposited. This offers not only a route to highly wear-resistant coatings but also a more general methodology for producing coatings from high-viscosity, high-performance polymers.

Title Non-steady state heating of substrate and coating during thermal-spray deposition
Output type: Journal article
Journal title: Surface and Coatings Technology
Month/year of publication: January 2005
Pagination: 82-90
Volume: 194
ISSN: 0257-8972
DOI: 10.1016/j.surfcoat.2004.05.017 ?
Research group: A - Materials Engineering
Co-authors: Gawne, D, Zhang, T
Other relevant details: All thermal-spraying operations require the spray gun to scan repeatedly over the substrate surface until the necessary coating thickness has been built up. This paper develops for the first time a quantitative model to predict the temperature-time distributions in the coating and substrate during scanning. This is practically important because the properties of coatings, particularly low-temperature materials like polymers, are crucially dependent on their thermal history. The research simulates the shifting temperature patterns over the coating due to the myriad of combinations of process parameter conditions and contributes to the general understanding of the control of thermal spraying.

Title Process Model of Plasma Enamelling
Output type: Journal article
Journal title: Journal of the European Ceramic Society
Month/year of publication: January 2003
Pagination: 1019-1026
Volume: 23
ISSN: 0955-2219
DOI: 10.1016/S0955-2219(02)00235-2 ?
Research group: A - Materials Engineering
Co-authors: Gawne, D, Zhang, T
Other relevant details: This paper develops a computational model to simulate the application of enamel to steel by plasma spraying. This is a radically new process for enamelling and has not been previously reported. The research predicts the process window necessary for successful deposition and this is validated by experimental trials. The work opens up the prospect of a completely new technology for enamelling. In particular, one in which large outside structures can be enamelled, which is impossible with the existing processes.
