TWI successfully deposits silicon carbide (ThermaSiC) coatings by thermal spraying techniques


TWI recently completed a project on the development of ThermaSiC coatings, a new product from Seram Coatings, Norway. TWI’s expertise has led to a breakthrough in the deposition of silicon carbide (SiC) based thermal spray powders, which are known to decompose at elevated temperatures.

TWI’s longstanding expertise in thermal spray coating technologies, and specifically the application of ceramic coatings, has enabled dense ThermaSiC coatings to be produced using conventional thermal spraying processes.

The TWI team, comprised of Dr Melissa Riley, Andy Tabecki, Feifei Zhang and Catherine Richardson, conducted a number of trials with a range of ThermaSiC powders to achieve high quality coatings using multiple spraying systems. The coatings offer significant potential in a number of applications across a wide range of industry sectors.

TWI is currently evaluating the coatings for a number of industrial applications, including an investigation of coating properties such as adhesion/cohesion strength, wear, erosion and cavitation resistance.
