THERMAL SPRAY OF SILICON CARBIDE (SiC) MADE POSSIBLE

We offer environmentally friendly, lightweight protection that extends the lifetime of critical components exposed to demanding environments with high wear, high temperature, and corrosion.

By strengthening the components’ resistance against these demanding environments, our customers experience lower maintenance costs, reduced downtime, decreased waste production and use of resources, and improved profitability.

We are the world’s first to have found a method for applying one of the world’s hardest substances, silicon carbide (SiC), as a protective layer with thermal spraying.

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 patented and owned solely by Seram Coatings AS, and is currently in field trials all over the world in major industries. We are ready to supply material for tests and pilots and welcome a discussion based on your needs.

What ThermaSiC is used for

The use of silicon carbide has enabled us to produce a uniquely durable and lightweight ceramic. No other coatings can match ours in resisting combinations of extreme wear, temperature, and corrosion. This combination of properties creates groundbreaking opportunities in a range of industries, from aerospace to glass production.

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.
