主要生产电机用电刷及刷架总成产品、各种特种石墨、陶瓷以及复合材料。
Mainly specialized in the production of brush for motor and brush holder assembly, various kinds of special graphite, ceramics and composite materials.
复合材料的电磨损体积与电刷的极性有关，正刷的磨损体积大于负刷的磨损体积；
The wear volume loss of positive brush is more than that of negative brush.
基于此，本文创造性地将复合电刷镀技术和纳米粉材料有机结合，成功制备了含纳米粉复合电刷镀层。
Base on these, a composite coating containing nano-powder is prepared by brush plating in this thesis.
