Experimental study of cavitation destruction of a protective composite polyurethane-based material

Studying the process of cavitation has remained relevant up to now. The reason for this is the multifactorial causes of cavitation and, as a result, the difficulty to prevent it. One effective way to fight cavitation destruction is to use specialized materials resistant to cavitation erosion in pumping equipment, in order to form a basis, for example, for manufacturing a new impeller.

In order to protect surfaces from cavitation, a specialized material has been developed based on polyurethane (DC-2), which makes it possible to resist cavitation without destroying the protective layer itself. An impact method was chosen to determine the effectiveness of applying the developed material. Its essence implies exposing a prototype to cyclic impact loading. To estimate the capability of the examined material to resist impact loading, we have designed samples in the form of cylinders with the thickness of the examined samples chosen based on the practical conditions for restoring equipment, namely, based on the optimal thickness of the applied material at restoration. Values for the layer's thickness were experimentally set within 2‒5 mm. Experimental loading of the examined samples has shown the high efficiency of using the developed material as protection during the cavitation destruction of a part for different loading modes. Given that the polymeric material DC-2 has a high level of liquid fluidity, it was proposed to add a thickener in the form of a glass-containing filler the type of "Orosil". In addition, considering the complex type of wear in pumping equipment, it was suggested to strengthen the polymeric material with finely dispersed abrasive particles. The current work involved an experimental testing of the effect of additional inclusions on the strength of the polymeric layer
