The influence of some factors such as drawing temperature, lubricate condition, drawing speed and mould size on the drawing formability of the shell of the notebook PC with magnesium alloy AZ31 sheet was studied.
Slide-wearing behavior of in-situ (Al_3Zr +Al_2O_3)_p/A359 composites prepared in A359- Zr(CO_3)_2 system was observed in the condition of boundary oil lubricant.
NiO/Al2O3 self-lubricating wear resistant ceramic matrix composite coatings with a microstructure consisting of Al2O3 primary dendrites and the inter-dendritic film-like NiO solid lubricant phase were fabricated on Al2O3 ceramic substrate by laser cladding with Al2O3-NiO ceramic powder blends.
1% OTC water-based lubricant compared with the hydraulic pressure oil, N46, its carrying capacity is 77.6% more than N46, and its lubrication effect enhances more than 10%.
Numerical results of the lubrication show that the differential viscosity is the principal non-Newtonian property affecting the lubrication, it is determined by the material parameters of the lubricant and is affected by the shearing rate.
The flows considered are applicable to a wide array of physical problems where liquid films are used to lubricate higher- or lower-viscosity core fluids, for which a concentric arrangement is desired.
Mucous cells apparently use some of the reserves to synthesize their secretions which lubricate cells and prevent cell damage during egestion of waste through the aboral pore.
It is shown that the presence of an external magnetic field directed along the axis of the bearing and a radial electric field leads to a considerable increase of the load-carrying capacity of the electrically conductive lubricating layer.
Numerical results of the lubrication show that the differential viscosity is the principal non-Newtonian property affecting the lubrication, it is determined by the material parameters of the lubricant and is affected by the shearing rate.
According theoretical analysis, both the methods will apparently change the electro-viscosity of the lubricant film so as to change the lubrication performances.
