Towards a Complete Model of DC Plasma Spray Coating Process

提高工业系统的性能取决于其组件承受苛刻工艺条件的能力。例如，为了提高燃气轮机的效率，需要更高的发动机温度。目前，发动机的最高工作温度受材料性能的限制，而不受燃烧过程的限制。为了提高一些发动机部件的性能，它们被涂上一层高熔点绝缘材料，以保护它们免受发动机高温的影响。热喷涂是沉积保护涂层最常用的技术之一。这是一项使能技术，其应用范围广泛，包括航空航天、汽车、化学加工、医疗植入物、发电、纸浆和造纸等。

Improving the performance of industrial systems depends on the ability of its components to withstand demanding process conditions. For example, to improve the efficiency of a gas turbine, higher engine temperature is required. The maximum operating engine temperature is currently limited by the material properties and not by the combustion process. To enhance the performance of some engine components they are coated with a layer of high melting point, insulating materials that protects them from higher engine temperature. One of the most commonly used techniques to deposit protective coatings is thermal spray coating. This is an enabling technology and its applications are wide ranging and include aerospace, automotive, chemical processing, medical implants, power generation, pulp and paper, etc.
