Laser cladding was investigated as a method for the in-situ synthesis of Ti-Al-C MAX phase coatings due to its speed compared with standard powder metallurgy methods, localized high power density and small heat affected zone. A 2Ti:Al:C coating on a pure Ti substrate was targeted using a stoichiometric elemental powder ratio, resulting in a dense, well bonded composite coating of three layers totalling 1.33 ± 0.02 mm thick. A thin overlayer containing Ti₂AlC MAX phase as the majority phase was produced at the coating surface, offering evidence for the feasibility of in-situ synthesis of a MAX phase by laser cladding with an elemental powder feed-stock. Quantitative phase analysis of XRD data indicated that the coating contained Ti₂AlC as the majority phase at the coating surface, along with a uniform distribution of TiC_0.64, Ti₃Al and TiAl. A maximum Vickers hardness of HV 811 ± 11 was observed in the sub-surface region of the coating.

研究了激光熔覆作为原位合成Ti-Al-C MAX相涂层的方法，因为它与标准粉末冶金方法相比具有更快的速度，局部高功率密度和较小的热影响区。使用化学计量元素粉末比将纯Ti基材上的2Ti：Al：C涂层作为目标，从而形成了一个密实且粘结良好的三层复合涂层，总厚度为1.33±0.02 mm。在涂层表面产生了一层以Ti ₂ AlC MAX相为主要相的薄覆盖层，这为用元素粉末原料通过激光熔覆原位合成MAX相的可行性提供了证据。XRD数据的定量相分析表明该涂层含有Ti ₂AlC是涂层表面的主要相，以及TiC _0.64，Ti ₃ Al和TiAl的均匀分布。在涂层的次表面区域观察到最大的维氏硬度为HV 811±11。
