Metal abrasive particle content in lubricating oil is an important index to judge the degree of deterioration of lubricating oil. Established a spiral electrode capacitance sensor by the finite element software ANSYS, the simulation result shows that the sensor is sensitive to the content of metal abrasive particle in lubricating oil, not affect by the metal abrasive particle itself. According ...

Abrasive machining is a widely employed finishing process for different materials such as metals, ceramics, glass, rocks, etc to achieve close tolerances and good dimensional accuracy and surface integrity. High efficiency abrasive machining is one of the important techniques of advanced manufacture. Combined with raw and finishing machining, it can attain high material removal rate like turnin...

Abrasive wear behaviour of WC-Co and Fe/Cu-based nanostructured coatings has been investigated under dry slurry conditions in this study. The retention coating constituents was confirmed together with the formation various metallic ceramic phases. rate one order lower than that micro-structured both conditions. Relatively higher abrasion resistance such compare to reference material because com...

The relationships between the parameters of structure heat‑treated steels and their abrasive wear resistance are established. At all temperatures final tempering hardened steel, there is a direct relationship its (the number elements in solid solution, density dislocations, size cementite particles intercementite distance) when sliding friction against loose particles. A computer program has be...

Stainlesssteel 403 is high-alloysteelwith good corrosion resistance and it’svery hard material. Abrasive water jet is an effective method for machining, cutting and drilling of stainlesssteel 403. In thispaperweoptimize the metalremoval rate of stainlesssteel 403 in abrasive water jet machining. The MRRisoptimize by usingthreeparameters water pressure, abrasive flow rate and stand-off distance ...

Abstrad-lo simulate general particle motion on the cross-section of a particle laden jetllow by using fractal point sets, a feedback control process is developed to ensurc the validity of nonlinear mapping techniques that transform an original fractal point set into the point set with any desired velocity profile. The points are utrlized to represent quantitatively functional ahrasive particles...

SEM analysis contains researches of tooth enamel surfaces of two populations. First group of samples is tooth enamel of prehistorically ancestor from Vucedol and the second group of samples is enamel of modern Croatian citizen. Even on small number of human teeth samples from cooperage site of Vucedol (3,000 BC) and today's Croatian people, we can conclude about chewing biometry of prehistorica...

In this paper, a finishing system with a mounted abrasive tool is proposed for finishing of metallic molds. The shape of the mounted abrasive tool is a ball-end type. When a metallic mold with curved surface is polished, the orientation of the mounted abrasive tool is not only fixed but also its revolution is locked. The motion of the mounted abrasive tool is feedforwardly controlled based on a...
