Blends of abrasive media are described that can be propelled via a pressurized air stream into a surface to remove contaminants or other undesired material from the surface. In addition to other advantageous properties, the disclosed abrasive media blends are capable of providing faster abrasion than conventional composite abrasives, but with significantly less dust than raw abrasives generate. The disclosed abrasive media blends include sponge abrasive media formed of a flexible, open-cell polymeric material bonded to one or more abrasive materials.

A stainless blasting medium is provided including blasting medium elements containing an austenitic chromium-manganese steel, the blasting medium comprising the austenitic chromium-manganese steel-containing blasting medium elements in a range of ≥90 wt.-% to ≤100 wt.-% relative to the total weight of the stainless blasting medium. The following further relates to the use of the stainless blasting medium for blasting surfaces, metal and non-metal surfaces, such as workpieces, in particular stainless workpieces.

Provided is a method of manufacturing a vibration transmission member for an ultrasonic treatment tool. The method includes: applying a release agent between a surface of a vibration transmission member configured to transmit ultrasonic vibration and a die for hot forging; performing hot forging to form the vibration transmission member after the applying of the release agent; removing, after the performing of the hot forging, a part of an oxide film formed in the performing of the hot forging by a first surface treatment; performing pickling to remove the oxide film after the removing of the part of the oxide film by a blasting treatment; and performing coating with a resin after the performing of the pickling.
