THERMAL SPRAY OF SiC MADE POSSIBLE

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.

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.
