PVD涂层技术通过在零部件表面形成一层物理气相沉积的薄膜，显著提高了零部件的耐磨、耐腐蚀性能，从而优化了船舶的性能和延长了使用寿命。这种涂层技术不仅适用于船舶的船体和某些零件，还特别适用于需要防水和耐腐蚀性能提高的部件，如发动机零件等。PVD涂层的优势包括较低的工艺温度，可以保持刃部的锋利，压缩残余应力可以阻止涂层裂纹扩散，以及更加细小的晶粒和更高的硬度，实现了非平衡的成分分布。此外，PVD涂层技术还具有环保优势，因为它是一个更加清洁的工艺过程，能够提供磁控溅射等技术，实现涂层的优化。
PVD涂层技术的应用对于提高船舶零部件的防水、耐腐蚀性能以及优化船舶整体性能具有重要意义，是船舶工业中不可或缺的技术之一。
