摘要：A method for removing a layer made of a first material from a surface of a body made of a second material is disclosed. The body is subjected to a pressurized jet containing a blasting medium composed of particles, where the pressurized jet at least intermittently has an Almen intensity of at most 0.35 Almen A, preferably at most 0.3 Almen A and particularly preferably at most 0.25 Almen A.

主权项：1. A method for removing a layer made of at least one first material from a surface of a body made of at least one second material, comprising the steps of: blasting the body with a pressurized jet containing at least one blasting medium composed of spherical particles and, in addition to the spherical particles, it contains, at least intermittently an alkali hydroxide lye that reacts chemically with the at least one first material of the layer; and ending blasting the body with the pressurized jet once the layer has been removed to a desired degree or the surface of the body has reached a desired predetermined degree of strength at a location at which the body was blasted by the pressurized jet.
