Profile: Techniques Surfaces UK Ltd. specializes in commercial operation and distribution of surface treatments and processes. A salt bath nitriding process utilizing sulphur activated non-polluting salts, operating at 570 degrees C. Sursulf effectively resolves problems associated with wear, fatigue and seizure in both steels and cast irons. The process produces a hard compact layer at the surface of the treated components with fine surface porosity. It effectively eliminates the potential for adhesive and abrasive wear, whilst introducing high residual compressive stress at the surface, which considerably improves fatigue resistance. In addition, the morphology and composition of the surface microlayer provides lubrication retention which considerably reduces the instability threshold of lubrication film breakdown.
