CrC, CrNiC and CrFeNiC deposits were successfully prepared from Cr³⁺-based plating baths with suitable amounts of complex agents and metal salts. The Cr-based alloy deposits could be hardened after rapid thermal annealing (RTA) at 500 °C for a few seconds. The highest hardness of 1800 Hv could be detected from the CrC deposit after RTA at 500 °C for 15 s. The hardening mechanism of annealed Cr-based alloy deposits is attributed to the precipitation of crystalline diamond-like phases. The diamond-like phase in a membrane shape was observed in the annealed-hardened CrC alloy deposits, while nano-sized membranes and particles were found in annealed-hardened CrNiC and CrNiFeC deposits, respectively.

使用合适量的络合剂和金属盐，从基于Cr ³⁺的镀浴中成功制备Cr C，Cr Ni C和Cr Fe Ni C镀层。Cr基合金沉积物可在500°C的快速热退火（RTA）几秒钟后硬化。在500°C的温度下进行15 s的RTA后，可以从Cr C沉积物中检测到最高1800 Hv的硬度。退火的Cr基合金沉积物的硬化机理归因于结晶类金刚石相的析出。在退火硬化的Cr C合金沉积物中观察到膜状的类金刚石相，而在退火硬化的Cr Ni C和Cr Ni中发现了纳米尺寸的膜和颗粒。Fe C分别沉积。
