Friction and wear characteristics of TiO2 nano-additive water-based lubricant on ferritic stainless steel The lubrication mechanisms are primarily ascribed to the formation of tribofilm and the ball-bearing effect of the TiO2 nanoparticles, respectively, on the ... H Wu,J Zhao,X Cheng,... - 《...
The amount of friction between two objects depends on the weight of the object and the surface materials of the object. Read Characteristics of Friction | Definition, Types & Causes Lesson Recommended for You Video: The Effect of Friction on Accelerating Objects Video: Coefficient of Friction |...
By using MMS-1G pin-disk high temperature and high speed friction and wear tester,the dry sliding friction and wear characteristics of CrNiMo steel-H96 copper couples in double-duty atmosphere of oxygen and carbon dioxide were studied,and its wear mechanism was analyzed.The results show that the...
ScienceDirect is phasing out support for older versions of Internet Explorer on Jan 12, 2016. For the best product experience, we recommend you upgrade to a newer version of IE or use a different browser: Firefox or Chrome. For additional information please see the ScienceDirect Blog page. ...
pressure, and as temperature decreases, the pore pressure gradually increases, the effective stress between soil particles gradually decreases to 0, and the formation of ice lenses leads to frost-heaving. At present, research on frozen soil melting and settlement is mainly based on the statistical ...

internal friction angle of coal 1. Introduction As the main path for gas migration, the pore and fracture network in coal seams primarily determines the permeability of the coal mass (Cui and Bustin, 2005). Coal permeability, as a key parameter influencing the gas flow rate in coal seams, ...
In addition, the number of FT cycles is an important factor for studying the effect of FT cycling. The number is larger, the physical parameters (e.g., elastic modulus, effective cohesion, internal friction angle and so on) of expansive soils become smaller unless the number exceeds a ...
