镍基复合材料是由镍基合金和其他材料（如碳纤维、陶瓷、硼、钛等）组成的材料，其中，镍基合金是材料的主体，其它材料的添加可以改变材料的物理性质和化学性质。

制备镍基复合材料的方法包括粉末冶金、真空热处理、电化学沉积和激光熔化等。其中，粉末冶金法是最常用的方法之一，其基本流程包括制备合金粉末、制备复合材料的预制体和热处理等步骤。

NMC材料具有高强度、高硬度、良好的耐磨性、耐高热、耐腐蚀性。

镍基复合材料最有前途的应用之一是做燃气涡轮发动机的叶片。用于镍基复合材料的基体有：纯镍、镍洛合金、镍铝合金。还有广泛应用的碳纤维增强镍基材料弹性假肢、涡轮机叶片。

镍基复合材料的增强体主要包括 SiC、碳及硼等的长纤维、短纤维、晶须和颗粒，增强相能够起到弥补基体材料缺陷的作用，比如提高镍基复合材料的耐磨性、蠕变稳定性、高温性能等。碳材料增强镍基复合材料主要包括：碳纤维增强镍基复合材料和碳纳米管增强镍基复合材料，而石墨烯增强镍基复合材料的研究还处于萌芽阶段。

镍基复合材料企业除常规招聘的职位外还有投资总监、组织发展(OD)、摩洛哥海外人力负责人、功能碳材料研发工程师、负极材料研发工程师、制造中心总监、行政主管（外派印尼）、机械工程师（外派印尼）、电气工程师（外派印尼）、采购工程师（外派印尼）、EHS工程师（印尼）、技术部经理（外派印尼）、财务总监（法国）、总经理

Nickel  matrix composites possess the properties like high wear resistance, low friction behaviour, high-temperature sustainability, and are suitable for energy applications. The incorporation of reinforcing components in the nickel metal matrix composites significantly improves the specific strength, microhardness, wear resistance, frictional behavior, creep, and fatigue characteristics, as well as provides exceptional surface quality in comparison to typical engineering materials.

In addition to regular recruitment positions, nickel based composite material companies also have positions such as Investment Director, Organizational Development (OD), Moroccan Overseas Human Resources Manager, Functional Carbon Material R&D Engineer, Negative Electrode Material R&D Engineer, Manufacturing Center Director, Administrative Supervisor (sent to Indonesia), Mechanical Engineer (sent to Indonesia), Electrical Engineer (sent to Indonesia), Procurement Engineer (sent to Indonesia), EHS Engineer (Indonesia), Technical Department Manager (sent to Indonesia), CFO (France), and General Manager.
