    Solid is one of the Four fundamental states of matter (the others being liquid, gas and plasma).The atoms in a solid are closely packed together and contain the least amount of kinetic energy. A solid is characterized by structural rigidity and resistance to a force applied to the surface. Unlike a liquid, a solid object does not flow to take on the shape of its container, nor .   Results of investigation on cavitation-erosion resistance of Cr–N coating deposited on stainless steel X6CrNiTi (1H18N9T) by means of the cathodic-arc method are presented. The evaluation of Cr–N coating resistance to cavitation erosion is based on the investigation performed in a cavitation tunnel with a slot cavitator and tap water as a medium. .

Solid-particle impingement erosion process on ductile metals can be characterized by the following periods: (1) Incubation or induction period-the exposure time span or abrasive charge during which there is a little or no weight loss. In fact, in a few cases there can be a slight weight gain caused by deposition or embedment ofFile Size: 1MB.

This paper describes an experimental study on the wall-thinning rate in deep erosion by liquid droplet impingement (LDI) in a pipeline for application to nuclear/fossil power plant.

The experiment is carried out in a spray jet apparatus, which allows the evaluation of local wall-thinning rate by the LDI erosion. in Fig. 3 for solid particle erosion of the Inconel alloy. The Inconel alloy showed the lowest erosion rate at 90° impingement angle, while Inconel exhibited the highest erosion rate at 45° impingement angle for all test temperatures.

This result is well-suits with the semi-ductile behavior of Inconel The unified damage. The relatively cheap option of organic coatings tends to perform poorly under high energy solid particle impingement but have a use as corrosion barrier coatings within low energy flow components, see Percy [ 4 ], whereas ceramic materials are usually too expensive to use, except in particularly critical applications.

Introduction Solid Particle Erosion (SPE) is a loss of material during repetitive impacts of solid particles and one of the primary reasons for the damage of power generation components. To study the effects of bubbles (or cavities) collapse on a solid surface, a rotating disk device was used here to create bubbles (or bubbles) in water.

In the apparatus, these bubbles are led to collapse on the surface of carbon steel (commonly used in structures and machine impellers), and so related to higher costs for the hydraulic machines industry when damaged by such Author: Gil Bazanini, José Divo Bressan.Kocks et al.
