A hard carbon coating and a method of improving its adhesion on components and tools that are subject to high loads or extreme friction, wear, and contact with other components. The metal carbide transition layer is located between an adhesion promoting layer directly deposited on the surface of the substrate and a top hard carbon coating. The metal carbide transition layer has a denser microstructure and improved mechanical properties to resist failure due to spallation. 一种硬碳涂层和一种提高其在承受高负载或承受极端摩擦、磨损和与其它组件接触的组件和工具上的粘合的方法。所述金属碳化物过渡层位于直接沉积在所述基材表面上的粘合促进层和顶部硬碳涂层之间。所述金属碳化物过渡层具有更致密的微观结构和改进的机械性质，以抵抗因散裂引起的失效。
