Cheap Brown Fused Alumina Wholesale Suppliers Canada

In order to estimate the initial kinetic energy consumption of particles during impact, two kinds of shapes and different incident angles of particles have been proposed(brown fused alumina). Sometimes glass balls and iron sand are also used to control the shape of wear particles(black silicon carbide). When solid particles of different sizes shoot from different directions to different shapes, their trajectories are different. The shape of wear particles also has a great influence.

Around each atom, there is a pair of adjacent atoms with the highest probability of occurrence, and the atoms cluster closely(brown aluminum oxide). The energy exchange between normal incidence of spherical particles and 30 ° incidence of sharp particles and spheres on the target surface has been studied(aluminum oxide abrasive). Nowadays, it is difficult to measure the actual sand velocity, but the particle velocity given in the literature is the velocity of liquid flow.ble.


(cheap brown fused alumina wholesale suppliers canada)The two kinds of erosion should pay attention to that the velocity of medium is different from that of particle in numerical value(white alumina). Generally, the velocity of medium can not be used to replace the velocity of particle. In hydraulic machinery, the relative velocity difference between sand and water flow is only tens of mm / s, that is, particles basically follow the flow(emery abrasive). The wear particles used in erosion test are usually SiO2, Al2O3 and SiC.


Generally, Al 2O 3 and SiC are polygonal(black corundum), which not only has strong erosion ability, but also can control the particle size range, which is beneficial to study the erosion mechanism of materials and shorten the experimental period. It is easy to analyze and calculate in the pitting experiment of glass ball and iron sand(silicon carbide grit). Soft abrasive such as nylon particle is also selected to study the influence of particle hardness on erosion.


When particles impact the material surface at a certain speed, energy exchange is inevita(silicon carbide abrasive). The particle size, shape, hardness and possible breakage in the erosion process all affect the erosion rate. In general, the wear rate increases with the increase of particle size in the range of 20 ~ 200um(aluminum oxide grit). However, when the particle size increases to a critical value, the wear rate almost remains unchanged or changes slowly.(cheap brown fused alumina wholesale suppliers canada)


Compared with circular particles, the wear of polygonal particles is 4 times larger than that of circular particles at 45 impact angles under the same conditions(pink corundum). The solid metal or alloy has its own structure, and the atoms are regularly arranged at the lattice nodes and vibrate slightly near the nodes(black aluminum oxide 70 grit abrasive media). When the metal or alloy is heated, the input heat increases the internal energy and the amplitude of atomic thermal vibration.


(cheap brown fused alumina wholesale suppliers canada)When the grains disappear to a certain extent, the metal or alloy loses its fixed shape and turns to liquid state(green silicon carbide). This external input of energy required to change a metal from a solid to a liquid is often referred to as the latent heat of fusion. Within the range of the group, the regularity of the structure of the solid metal products slightly lower than the melting point is maintained(synthetic corundum). This phenomenon is called "size effect".
