Abstract
Wetting properties of silicon-carbide ceramic (SiC) surfaces were studied experimentally. The samples of silicon-carbide ceramic were made by spark plasma sintering from two types of powders: commercial and ultradispersed obtained by plasma dynamic synthesis with and without additives. The measurements of static contact angle characterizing wetting properties were conducted by the optic shadow method. The use of additives while sintering of silicon-carbide powder (obtained by plasma dynamic synthesis) was found to lead to an improvement in the wettability of SiC surfaces. A coarse-grain structure and large number of pores in sample of silicon-carbide ceramic made of commercial powder are the main reasons of complete wetting of this sample surface. The sample with greater density was obtained after sintering this powder with additives. As a result, this led to an increase in the static contact angle on this sample.
