METHOD FOR VIBROPERCUSSION TREATMENT OF PARTS MADE OF TITANIUM ALLOYS Russian patent published in 2021 - IPC B24B31/67 

FIELD: metals.

SUBSTANCE: at the first stage, the method includes cleaning the surface of the part by vibropercussion abrasive treatment with ceramic granules in a vibration machine. At the second stage, the surface of the part is strengthened in the vibration machine by vibropercussion treatment with steel balls. The intensity of the vibropercussion strengthening is controlled by measuring the bending of at least two steel witness samples. At the third stage, the surface layer with microcracks, saturated with contact-plated iron, is removed by vibropercussion abrasive treatment in a vibration machine with ceramic granules with sizes smaller than up to 30% of the sizes of the granules used at the first stage. The thickness of the mechanically removed surface layer is controlled by measuring the thickness of at least two control witness samples made of the same brand of material, according to the same technological process, as the treated material, using material thickness control sensors.

EFFECT: reduction in the harmful impact of the technological process on the environment and facilitated organisation of the technological process with the maintained efficiency of removing contact-plated iron and increased fatigue resistance of parts made of titanium alloys.
