Abstract:
The effects of organic silicate on the frication performance of 45
steel/HT150 pair are studied by an improved frication apparatus. The
reagent of organic silicate is added to the pair, and then the frication
experiment is carried out under variable load, constant velocity and air
conditions. The results show that there is ivory-white film on the
surface of 45 steel. Investigation by microscope indicates that many
particles, such as the elements of organic silicate are embedded into
the surface. The micro-penetration hardness and surface roughness are
greatly increased and decreased respectively, which demonstrate the
pronounced abrasion-resistant effects of organic silicate.
