摘要：

随着全球能源和环境保护问题的日益突出，人们在探索各种各样的能量回收方法。作为一种固态能量产生装置，热电发电装置能将温差转化为电压，从而实现车辆尾气废热的能量回收、提高总体能量利用效率。最近，出现一种新型可产业拓展的热喷涂工艺，可以用于热电发电装置的集成制造，直接用在排气管上。本文对应用于车辆尾气废热回收的热电材料和热喷涂工艺流程的前沿技术进行了综述。它们也可以用于热电厂、制造过程和其他场合的能量回收。

Abstract:

With the global concerns on energy and environmental issues, various approaches of energy harvesting have been explored. As a solid state energy generator, Thermoelectric Generators (TEGs) can convert the temperature gradients to electrical voltage, thus recovery the energy from vehicle exhaust heat and increase overall efficiency. Recently a new industry-scalable thermal spray process has been extended for the integrated manufacturing of thermoelectric generators on the exhaust pipes directly. This paper is to provide a timely review of the state-of-the-art on thermoelectric materials and thermal spray fabrication process for the
applications of vehicle exhaust heat recovery. They can also be used for energy harvesting in the power plants, manufacturing processing, and many others.
