Composite powder composition for ceramic coating and ceramic coating, and preparation method thereof
The invention discloses a composite powder composition for a ceramic coating and a ceramic coating, and a preparation method thereof. The composite powder composition comprises an yttria stable zirconia powder and graphene nanosheets. The ceramic coating, which is obtained by spraying the composite powder composition on a metal substrate, has obviously higher wear resistance than the pure-phase yttria stable zirconia coating, can obviously reduce abrasive dust generated by friction under high-load conditions, and obviously lowers the friction factor and average abrasion rate. The invention provides a feasible solution for enhancing wear resistance of the ceramic coating. Besides, the method has the advantages of high efficiency, favorable repeatability and the like, and is simple to operate and suitable for large-scale production.
