Paper deals with copper CW004A surface characteristics evaluation after
disintegration by enhanced pulsating water jet. The main aim was identify and
describe areas of pulsating water jet disintegration effects on material with using
circular nozzle diameter. 25 samples were disintegrated at change traverse speed
v = 0.1 – 20 mm·s-1, for assessment of individual areas formation. Surface
characteristics were evaluated based on surface roughness parameters Ra [μm],
Rz [μm], Rp [μm], Rv [μm], mass material removal Δm [mg.mm-1] and volume
material removal Vm [mm3]. Based on experimental investigation, three areas of
pulsating water jet effects on material were determined.
