24-12 TESTAREA COMPORTAMENTULUI LA EROZIUNE CAVITAŢIONALĂ A UNUI ALIAJ NEFEROS CU 88 % ALUMINIU
CAVITATION EROSION BEHAVIOR TESTING OF A NON
FERROUS ALLOY WITH 88 % ALUMINIUM
This paper presents cavitation erosion behaviour testing of the
nonferrous alloys AlSi12 with 88 % Aluminium. Vibratory cavitation tests were
made on a cavitation stand in the laboratory, using the stationary specimen
method. This alloy is not subject to cavitation erosion in practical applications,
as is the stainless steels used in hydraulic turbines, but the experimental
research highlight the behaviour of a material (AlSi12, in this case) when the
period of time testing are different. Research results are presented through
graphs and representative images.
