THE HARDEST THERMAL SPRAY COATING IN THE WORLD!
THERMAL SPRAYING OF SILICON CARBIDE (SIC) MADE POSSIBLE
Thermasic - Silicon Carbide based powder for thermal spray
Seram Coatings´ product ThermaSiC enables SiC (Silicon Carbide) to be applied as a coating by thermal spraying for the first time. ThermaSiC provides superior coating performance in corrosive and abrasive environments as well as at high temperatures (up to 1500° C in air and 2400° C in inert atmosphere). As SiC is one of the worlds hardest synthetic materials (only exceeded by diamond, cubic boron nitride and boron carbide) and possesses lower density than competing solutions such as WC (tungsten carbide), ThermaSiC gives your products a longer lifetime, lower maintenance costs as well as giving you a competitive advantage.
Compared to vacuum deposition methods (PVD or CVD), thermal spray of ThermaSiC deposition rates and efficiency and has a significantly lower cost. In addition ThermaSiC is specially designed to be used in atmospheric thermal spray conditions suppressing the need for expensive and size limiting vacuum chambers. ThermaSiC is patent pending and owned by Seram Coatings AS and is currently being proven in pilot projects in several industries. We are ready to supply material for tests and pilots and welcome a discussion based on your needs.
The properties of ThermaSiC thermal spray coatings
The properties of SiC makes it highly attractive as a coating for many industrial applications. Mainly due to extreme hardness in combination with a low friction coefficient and to being chemically inert. It also has a very low density compared to e.g. Tungsten Carbide (WC), which makes it attractive in applications where weight is of importance. The low density, together with the low price of bulk material, makes it a cost-effective competitor to most hard coating materials on the market.
The most relevant applications of thermally sprayed SiC are high wear resistant coatings, where WC is primarily used. Typical applications would be sliding surfaces, rollers, machine parts for the petrochemical and chemical industry, gate valves, pumps, slides, ball valves, mechanical gears and seals, any kind of wear protection, also in combination with corrosion protection. Particularly relevant are sliding and abrasion applications.
Seram Coatings is the only supplier of SiC-based thermal spray coatings. ThermaSiC can be applied with key thermal spray processes such as for example atmospheric plasma spray, detonation gun and HVOF.
- Superior corrosion and abrasion protection – also at high temperature (up to 1500° C in air and 2400° C in inert atmosphere)
- Very high hardness: up to 1700 HV (and we aim for even higher)
- High resistance against most kinds of wear types
- High thermal conductivity (superior to stainless steel)
- Low density (ca. 3g/cm3) – builds less weight to substrate
- Very attractive properties and pricing compared to CVD/PVD and WC-based coatings
The road ahead
We are now testing our product for different applications in a range of different industries. New industrial partners are still welcome to collaborate with us, and we will focus on verifying the product capabilities for different applications.
