Gouging abrasion

Abrasive wear can be classified into three types. Gouging abrasion is a high stress phenomenon that is likely to be accomplished by high comprehensive stress and impact. Grinding abrasion is a high stress abrasion that pulverizes fragments of the abrasive that become sandwiched between metal faces. And erosion is a low-stress scratching abrasion.

In wet ball milling the grinding rate increases with sohds content up to 70 wt % (35 vol%), as Fig. 20-33 shows, due to pulp rheology. Examination of gouge marks indicated that most breakage was by impact of balls on particles rather than by abrasion.

The majority of engineering materials are heterogeneous, composed of phases with considerable differences in hardness. When an abrasive particle is small, the presence of coarse, hard, phases in these alloys can considerably strengthen the material s resistance to abrasive wear. But if the abrasive particle size is comparable to the scale of heterogeneity of the material, then gouging out the hard material from the structure leads to an increased wear rate. Abrasion can be limited by ... 

The poor pad performance on the Man (Kibble) Hoist, the scoring of the disc and gouging of the pads encouraged the OEM to trial a new pad material. Performance tests on the original and replacement pads during the hoist tests gave friction coefficient values ranging from 0.276 to 0.401. The replacement pads proved to be a particularly harsh pad material, rich in abrasive... 

Hypalon s resistance to abrasion is superior to that of natural mbber and many other elastomers by as much as 2 to 1. Good resistance to impact, cmshing, cutting, and gouging, and other types of physical abuse are also present in this elastomer. 

Harder, less friable materials clean faster and are more economical than softer, friable abrasives. However, hard materials produce more cutting and gouging. If surface depletion due to cutting and gouging is unacceptable, a softer material must be used, at the expense of speed. 

Surfaces exposed to frequent viewing should be free of blisters, runs, nicks, gouges, blemishes, or other abrasions that would detract from the general appearance of the finish. Faceplates must also be securely fastened to the PCB, that is, tightly enough to prevent physical movement. 

Before loading or unloading, an external visual inspection of each ammonia tank car should be performed. If the tank car tank, or jacket if the tank is insulated, shows evidence of abrasion, dents, gouges, severe cor-... 

The extremely high molecular weight of HOPE combined with its very low coefficient of friction produces an excellent abrasion-resistant product which is resistant to gouging, scuffing, and scraping.
