Abstract

The issue of anti-frost surface treatment is a current research topic, especially in the transport and energy industries. Ice and its formation, adhesion and accumulation can cause serious problems on the surface of wind turbines, solar panels, power lines, roadways, in aircraft industry as in everyday life. These aspects can reduce energy production efficiency, increase energy consumption, cause mechanical or electrical failure, and increase security risks. This article deals with the wettability of surface treatment and its influence on the formation of icing on metal surfaces. In this study, new method for fabricating anti-icing coating was employed. The metal samples were first surface treated and afterwards the anti-icing coating for titanium alloy samples was applied and coating properties were examined. Various surface treatment steps were tested for the coating anti-icing properties. The formation of icing was experimentally tested on modified surface of metal substrates. Wetting properties of the titanium surface was evaluated by contact (wetting) angle measurements. The surface structure of the metal samples was examined by SEM (Scanning electron microscopy). Testing of anti-icing properties of the surface treatment took place indoors. Physical and mechanical properties of the samples were evaluated before and also after the testing at low temperature.
