Ensuring the Informational Effectiveness of Ultrajet Diagnostics for Quality Control of Composites

A new technique for examining composites by means if ultrajet diagnostics is considered. The scientific approach is based on imitating material fatigue tests in accelerated mode and evaluating composites for adhesive strength at alternate loads. Ultrajet diagnostics will allow ensuring the performance adequacy of resource strength calculations while designing items from composites by rapidly determining the necessary parameters of physical mechanical properties in the course of their design and process development. A Ti6Al4V titanium alloy powder sample made by selective laser melting is used as an example to show that the geometric parameters of hydroerosion are associated with the surface defects of the sample, its stress–strain state and the in-growth path and direction followed by the scanning laser beam.
