Surface Heat Treatment
Surface heat treatments are a group of metallurgical processes that focus on modifying the properties of a material’s surface layer while leaving the core unchanged. These treatments are applied to enhance surface hardness, wear resistance, corrosion resistance, and other specific characteristics.
Flame Hardening
Flame hardening is a distinguished method in the domain of heat treatments for steel components, including gears. The technique uses an oxy-fuel flame to selectively heat parts to their austenitizing temperature, followed by a quenching process.
Carbon Restoration
Investment casting is method of production that allows for creation of parts with complex geometries that require little to no machining for them to be put into service. As the castings cool after pouring decarburization can occur at the part surface. Decarburization, frequently truncated to decarb, can lead to a range of negative consequences spanning from reduced wear to premature failure during service. The most common way to remediate this without the need for additional material removal is to perform a specialized form of heat treatment called carbon restoration.
Carburizing
Welcome to our detailed exploration of the carburizing heat treatment process for machined gears, machined parts, and stampings. This transformative method offers technical benefits, especially for steel components, ensuring they’re primed for high-performance applications.
Carbonitriding
Carbonitriding is a sought-after heat treatment process due to the significant enhancement to wear resistance, surface hardness, and other pivotal properties of steel components subject to this specialized form of heat treatment. At ThermTech, we leverage this process, especially for plain carbon steels, to ensure gears, machined parts, and stampings stand up to rigorous use.
Nitriding
ThermTech is a pioneering figure in providing gas nitriding heat treatment for machined parts, stampings, and tooling. Gas nitriding, a heat treatment technique, introduces nitrogen into the surface layer of steel components using an ammonia gas atmosphere at elevated temperatures. It has emerged as an essential process, particularly for case-hardened machined components with wear surfaces.
