“…With the development of technology, new processing methods such as ultrasonic polishing and laser polishing, which overcome the difficulties of traditional processing methods for high-precision processing, effectively improve the quality of the processed surface. Zhang et al [ 1 , 2 , 3 ] used ultrasonic waves to polish the material surface; compared with traditional polishing methods, the use of ultrasonic polishing can effectively reduce the surface roughness of the material. However, due to the complexity of the technology and the material removal mechanism, which is not yet completely clear, it is not possible to optimize the process parameters effectively, which limits its widespread use.…”

Laser polishing was used to reduce the surface roughness and improve the surface properties of alumina ceramics. In this paper, a response surface experimental design scheme is used to establish a mathematical model based on the Box–Behnken central combination principle, with the surface roughness as the optimization target to optimize the optimal process parameters for the laser polishing of alumina ceramics, to suppress the polished surface cracks by preheating the material, and to study the changes of surface properties of laser-polished alumina ceramics under different preheating temperatures. The optimal laser polishing process parameters were optimized by response surface experiments with a scanning speed of 323.5 mm/s, a laser power of 73.63 W, a pulse frequency of 2.3 kHz, and a scanning spacing of 0.09 mm; compared with the initial surface roughness of 4.67 μm, the polished surface roughness was 0.96 μm under the experimentally optimized polishing parameters, and the surface cracks were suppressed after the preheating treatment. The surface roughness was further reduced to 0.74 μm, and the surface wear coefficient was reduced from 0.5939 to 0.5725, while the surface hardness was increased from 1810 to 2063 HV. Optimization of the laser polishing process parameters through the response surface can significantly reduce the surface roughness of the material, while the flame preheating, assisted by the laser-polished surface wear resistance and hardness, is improved.

“…Therefore, by applying a swirling pulsating flow, cavitation process can be induced already at water pressure of 30 bar. The development of this method began with the use of cavitation generating nozzles for surface processing, for example, drilling [17,18] or polishing [19]. Cavitating jets use the energy emitted by bubbles collapse to increase impact force [14].…”

The paper presents a novel, environment-friendly method for removal of foulants from surfaces. Various adhered foulants as solid particles and the like can be detached from surface by cavitating pulsating water jet which is generated in specially designed nozzles and directed on the surface being cleaned. The objectives of this research were to establish fouling removal efficiency of developed cavitation generating head and residual water removal efficiency of its cyclone-type water removal system which is used to remove water residuals from cleaned surface. It was experimentally established that 100% abrasive particle removal efficiency from metal surface is achieved when distance between head outlet and surface is varied from 1 to 8 mm. The most effective is cavitation generating head with water removal system in which the flow is drawn in the same direction as the air flow is supplied inside the head. If this water removal system is used, the average visible water content on the metal surface equals to 1.4%, while when the flow directions are opposite, water content is increased to 27.2%.
