The invention discloses a novel electric heating coating. The novel electric heating coating sequentially comprises 1) a base material, 2) an alloy layer, 3) a ceramic layer and 4) a metal copper layer, the thickness of the alloy layer is 30-50 microns, the thickness of the ceramic layer is 90-130 microns, and the thickness of the metal copper layer is 10-1000 microns. The novel electric heating coating can be used for deicing, air conditioner heating and the like in the fields of automobiles and the like. A preparation method comprises the following steps of a) carrying out inspection and surface pretreatment on the base material, b) depositing the alloy layer on the surface of the base material by using a thermal spraying method, c) depositing the ceramic layer on a bonding layer by using a thermal spraying technology, d) depositing a copper coating on the ceramic layer by using a cold spraying technology and carrying out annealing treatment, and e) finally, corroding the required copper circuit by adopting technologies such as chemical corrosion and the like. The coating sprayed by adopting the cold spraying technology has the electrical property equivalent to that of pure copper, so that the heating efficiency is relatively high and the energy-saving effect is relatively good.

    本发明公开了一种新型电加热涂层,所述新型电加热涂层依次包括:1)基材;2)合金层;3)陶瓷层;4)金属铜层;所述合金层厚度为30~50μm;陶瓷层厚度为90~130μm;金属铜层厚度为10~1000μm,可用于汽车等领域的除冰、空调制热等。该制备方法包括:a)对基材进行检验及表面预处理,b)使用热喷涂的办法在基材表面沉积合金层,c)使用热喷涂技术在粘结层上沉积陶瓷层,d)使用冷喷涂技术在陶瓷层上沉积铜涂层并进行退火处理;e)最后采用化学腐蚀等技术腐蚀出所需的铜电路。其中,采用冷喷涂技术喷涂的涂层具有与纯铜相当的电学性能,因而具有较高的加热效率和较好的节能效果。
