The Mechanism of Abrasion of Vulcanized Rubber

Rubber Chemistry and Technology, 1964
Abstract The authors investigated the abrasion of a number of vulcanized rubbers with the sliding of a smooth steel indenter. Abrasion was achieved by repeated action of an indenter, moving reciprocally along one and the same portion of the surface of the rubber.

Concrete–ice abrasion mechanics

Cement and Concrete Research, 2015
Abstract The mechanisms of abrasion of concrete by ice are investigated by review of lab and field studies, wear theory, fracture-, contact- and poromechanics. Experience indicates that ice abrasion does not require freeze/thaw cycles. Three distinct mechanisms may contribute to abrasion damage of concrete: (1) asperities of ice sliding on concrete ...

Mechanism of Abrasive Wear in Nanomachining

Tribology Letters, 2011
In this study, nanomachining is utilized to investigate the abrasive wear mechanism that produces a nano scale groove on a bulk material. Two different tools (Berkovich and Conical) with the same tip radius (100 nm) but different edge geometries were used for machining both Cu- and Ni-coated materials with a nanoindenter that was equipped with a nano ...

Basic mechanism in free abrasive grinding

Applied Optics, 1974
Abstract This work reports an experimental study on a long standing, optical, grinding technique. In particular it concerns scratching due to oversize particles in the abrasive and how they are controlled within the grinding process itself. The edge definition of the upper working piece (specimen or lap) controls admission of oversize particles to ...

Mechanics of the Abrasive Cutoff Operation

Journal of Engineering for Industry, 1967
The abrasive cutoff operation in which a high-speed disk is fed radially into a steel member is analyzed. The feed rate and the wheel speed are the chief variables of importance. Cutting forces and wheel wear rate are analyzed in terms of chip size, grain spacing, and the length of work in the direction of cut.

Surfaces with Sustainable Superhydrophobicity upon Mechanical Abrasion.

ACS Applied Materials and Interfaces, 2016
Surfaces with sustainable superhydrophobicity have drawn much attention in recent years for improved durability in practical applications. In this study, hollow mesoporous silica nanoparticles (HMSNs) were prepared and used as reservoirs to load ...

Abrasion groove sizes and shapes in relation to the mechanism of abrasion

Wear, 1978
Abstract Average abrasion profiles for polymer and metal surfaces abraded with emery cloth grades of 00, 320, 180, 100 and 40 have been obtained using a frictional method. Profiles using 180 grade silicon carbide abrasive are compared with those obtained using 180 emery abrasive.

Abrasive Wear Mechanisms in Steels

Journal of Lubrication Technology, 1982
Abrasive wear tests have been carried out on three steels and a number of pure metals using a pin-on-drum instrument. Each steel was tested at several different hardness levels attained by varying the heat treatment and while the results show a relationship between abrasion resistance and hardness, this was not the linear relationship found by Kruschov

Concrete-Ice Abrasion Mechanism

Volume 8: Ian Jordaan Honoring Symposium on Ice Engineering, 2015
There are not many data related to the mechanism of concrete-ice abrasion published. Some of researches try to find similarities in concrete-ice abrasion mechanism with various wear mechanisms from tribology, others propose their own theory. In general, ice abrasion of concrete has some similarities, noticed by researches, with wear mechanisms of other

Wear mechanisms with coated abrasives

Wear, 1974
Abstract A metallographic study is described of the grit failure mechanisms operating with coated abrasives when grinding a wide variety of engineering materials. Scanning electron microscopy has been used to both characterise and monitor the incidence of the various grit failure mechanisms for a standard aluminium oxide resin-bonded belt and a ...
