Study of cellulase adsorption on indigo particles and insoluble cellulose, as well as experiments on indigo interaction with immobilized amino acids together with theoretical analysis of three-dimensional structures of enzyme molecules, provided an evidence that certain cellulases, which have hydrophobic domains (clusters of closely located aromatic and non-polar residues) on their surface, may...

Abrasive machining in general and grinding in particular are processes, which increase their importance with high demands on accuracy of surface finish. The chip thickness is an evaluating variable to describe the quality of ground surface as well as the performance of the overall grinding system. A significant characteristic that distinguishes ceramics from metals is their low fracture toughne...

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...

The orthopedic stent wire is one of the critical medical components, which mainly used for replacement physically damaged parts in human body. Therefore, a smooth surface and lack toxic substances on this component are highly demanded. In study, magnetic abrasive finishing (MAF) process was carried out using non-toxic compound (a mixture iron powder, diamond particles, cold cream, eco-friendly ...
