BoracarbTM   The Oxidation-Resistant and Wear-Resistant Ceramic

Boracarb TM is an evolutionary breakthrough that enables GRAPHITE to be engineered as a new high-temperature ceramic material for use in oxidizing environments above 900 C (1650 F) has been developed  by ZYP Coatings.

Graphite offers many useful properties – excellent thermal shock resistance, low cost, easy machinability, chemical resistance, good thermal conductivity and more. However, its main limitation is oxidation in air above about 450 C. The ZYP-developed Boracarb TM process is an ultra-high-temperature gas phase treatment that produces a protective “case” conversion layer similar in concept to carburizing or nitriding of steel. With the Boracarb TM treatment, graphite is protected from oxidation in air up to 900 C (1650 F) for THOUSANDS OF HOURS.

In the past, short-term graphite oxidation protection has been provided by ceramic paints, and coatings.  However, these have provided limited protection and are easily damaged in use. The Boracarb TM case depth provides long-term protection and is robust in use. The Boracarb TM treatment also provides an extremely WEAR RESISTANT LAYER which is also ELECTRICALLY INSULATING, thereby allowing graphite to be used in new and expanded areas
