1 and 2, show for the same material (alloyed steel 40Cr10, bronze CuAl III RNR) independent by working fluid (distillated water, drinking water and sea water), mass losses are produced only by mechanical effect of cavitation erosion, without substantial contribution of surface or intergranular corrosion.
Cavitation liquids and probes were chosen so, to reveal both cavitation erosion independence by chemical corrosion, through effect of upper mentioned factors on cavitation damages, as well as the plurality of cavitation and chemical corrosion effect.
Three previous studies of mesh erosions in women with an intact or missing vaginal apex produced conflicting results.
Reports of mesh erosions after sacral colpopexy suggest that 3%-16% will erode, usually 4-24 months after surgery, she said.
A trend toward increasing use of permanent mesh for sacral colpopexy, combined with concerns about synthetic mesh erosions, led them to focus on sacral suspensions that used polypropylene mesh.
