| چکیده |
N, N"-Ethylenedistearamide (EBS) and poly(ethylene-co-octene) (EN) were selected as internal lubricants for ABS to improve its friction characteristics. The effects of additive type, part surface roughness and testing temperature on the friction characteristics were investigated and found that at 80ºC, kinetic COF were lower than at 23ºC owing to thermal softening and melting of rubber components of the contacting surfaces. EN was more effective than EBS in reducing COF and double amplitude of stick-slip curves of ABS both at 23ºC and 80ºC due to the decrease in surface energy and adhesion between moving surfaces with EN added. At 23ºC kinetic COF of ABS+5wt%EN showed strong dependence on the surface roughness while this was not the case for ABS and ABS+0.5wt%EBS. |
