Influence of Homogenization Heat Treatments on the Mechanical, Structural, Biodegradation, and Cavitation Behavior of Some Alloys in the ZnMg(Fe) System

Crystals
This paper presents the biodegradation and cavitational erosion behavior of new zinc alloys in the ZnMgFe system. The alloys were heat-treated through homogenization at 300 °C and 400 °C, with maintenance times of 5 and 10 h each.

Link between in-nozzle cavitation and jet spray in a gasoline multi-hole injector [PDF]

, 2013
The importance of cavitation inside multi-hole injectors has been addressed in many previous investigations where the cavitation formation and its development, fuel spray characteristics and atomisation have quantified. Different types of geometrical and

Cavitation erosion resistance of some refractory ceramics

Cavitation erosion can be observed as a hazardous phenomenon that has a significant impact on the behavior and lifetime of engineering materials under operating conditions. This phenomenon is a result of fluid flow conditions and can cause the formation of pits and defects, resulting in not only reduced mechanical properties but also a potential risk ...
