Brown Aluminum Oxide Grit Manufacturers China

After sintering, the bulk density of abrasive tools will gradually increase, the microstructure of abrasive tools will be more compact, and the porosity will also decrease(green carborundum). There are a lot of pores in the cross section of abrasive tools(brown aluminium oxide manufacturer). When the mass fraction of binder increases to 18%, the microstructure of abrasive tools will begin to become compact and knot The total porosity of the bridge also decreased.

Therefore, the bond is not evenly distributed among the abrasive particles(brown aluminium oxide), thus improving the binding degree of the binding phase and abrasive particles, and the bond bridge connecting the abrasive particles is relatively long and thin, and the bond degree between the abrasive particles is poor(brown fused alumina for grinding). In addition, the mechanical strength of the bridge itself is affected by the fact that the bridge is not dense and there are a lot of pores.


The crack tends to expand at the lower strength(white alumina). The cross section of CA3a is relatively rough. When the abrasive tool breaks, it basically passes through the combination phase and breaks along the interface between the abrasive particles and the combination phase. The breaking strength of the abrasive test strip is relatively low(brown aluminum oxide blast media). For brittle materials, it can be found that with the increase of binder content, fracture occurs in the form of crack propagation.


Compared with the micro morphology of ca3h cross section sintered at 850 ℃(black aluminum oxide), the high temperature wettability of bond 3H to ceramic corundum abrasive particles is better, the coating area of bond to abrasive particles is large, and the combination between bond bridge and abrasive particles is mostly surface combination(silicon carbide companies). When the mass fraction of binder is 16%, the microstructure of abrasive tools will be loose, and the binding bridge will be relatively slender.


The binding agent is evenly distributed among the abrasive particles, the binding bridge is coarser and shorter, and the binding degree with the abrasive particles is better(pink aluminum oxide). In addition, the bonding bridge is relatively compact, and there are only a few pores in the bonding bridge, and most of them are small pores, which is conducive to the improvement of the mechanical strength of the bonding bridge itself(white aluminum oxide 120 grit). Ca3h cross section is relatively smooth.


When the abrasive tool breaks(brown fused alumina), it breaks through the binding phase and along the interface between the abrasive and the binding phase, and it also breaks through the abrasive, with high failure strength. The high temperature wettability of bond 3a to ceramic corundum abrasive particles is poor, the coating area of bond 3a to abrasive particles is small(brown fused alumina grit), and the combination between bond bridge and abrasive particles is mostly point combination.


Compared with the above-mentioned micro morphology of the cross section of the ceramic corundum abrasive with different binder content(silicon carbide price), the micro structure of the cross section of the abrasive is more compact, the binding bridge connecting the ceramic corundum abrasive particles will become stronger(black silicon carbide suppliers), and the pores between the abrasive particles and the abrasive particles, and between the abrasive particles and the binder will gradually reduce.


In these two stages, the bending strength of the test strip of ceramic corundum abrasives increases greatly with the increase of the amount of binder(brown aluminum oxide). This is because when the content of binder is relatively low, the binding bridge is relatively long and thin, increasing the amount of binder, the binding bridge will become more thick(aluminium oxide grit 24 mesh), leading to the bending strength of the test strip of ceramic corundum abrasives Significantly improved.
