An apparatus for removing a coating from a substrate comprises a nozzle with an inner conduit having an orifice and an outer conduit coaxially arranged about the inner conduit and defining an annular opening between the inner and outer conduits. The nozzle is configured to direct a liquid stream through the orifice toward the coated surface and direct a gas flow through the annular opening such that the gas flow surrounds the liquid stream as the liquid stream moves towards the coated surface.

The present disclosure discloses an oscillator for stirring and vibration of sponge abrasive blast, and relates to the technical field of sponge abrasive blasting machines. To overcome the technical deficiencies of a screw rod propulsion structure adopted by an existing sponge abrasive blasting machine, the oscillator comprises a tank, a stirrer disposed in the tank and a power mechanism for driving the stirrer, wherein the stirrer comprises a drive shaft in a flat strip-shaped structure, an upper end of the drive shaft is in transmission connection with the power mechanism, a bottom end of the drive shaft is inserted into a discharge channel of the tank, and each side wall of the drive shaft is connected with more than two flexible stirring arms in spring structures. With the adoption of the drive shaft in the flat strip-shaped structure, a part of an airflow in an airflow pipeline can be intermittently introduced into the tank to blow off a sponge abrasive stuck in corner positions during the rotation of the drive shaft, and meanwhile, under the stirring and vibration of more than two flexible stirring arms in the spring structures connected to each side wall of the drive shaft, the discharging is smooth and thorough.

An apparatus to remove at least a portion of a coating from a coated surface of a substrate may include a nozzle assembly and one or more nozzle-heads. Each nozzle-head may include at least one nozzle tip and a cavity configured to receive a portion of the coated surface of the substrate. The nozzle tip may be configured to direct an angled stream of an etchant on the substrate as the nozzle assembly moves along the length of the substrate. One or more sensors may measure a warpage of the substrate along the length of the substrate, and a controller may move the nozzle-head orthogonal to the direction of nozzle-head movement based on the measured warpage.
