Title: Wear resistance treatment for sliding member
Inventor: OZAKI YOSHINORI
IPC: C23C4/08
Filed: 1992-07-10
Abstract: PURPOSE:To apply wear resistance treatment for a sliding member minimal in the amount of fluctuation in a friction coefficient due to changes in braking conditions and excellent in wear resistance. CONSTITUTION:A mixture of Fe-C powder and aluminum bronze powder in the amount of 10-50% based on the weight of the Fe-C powder is thermally sprayed onto the sliding surface of a sliding member. Because Fe-C powder is used instead of Fe-C-Cr powder, hardness is not increased and a friction coefficient of the desired level can be secured. Further, by mixing aluminum bronze powder, the difference in the thickness of a rotor film due to the difference in braking conditions is minimized and, accordingly, the amount of fluctuation in a friction coefficient is minimized, by which the friction coefficient can be stabilized. Moreover, a rotor film containing organic components is formed and this film acts as protective film for the thermally sprayed layer, by which wear resistance can remarkably be improved. As a result, the thickness of the thermally sprayed layer can be reduced to about 300mum, and cracking and peeling due to thermal stress can be prevented.

IPC: B08B3/08
Filed: 1999-06-29
Abstract: PROBLEM TO BE SOLVED: To efficiently and surely remove cutting chip stuck to a pipe stock by making the cleaning speed in a cut zone of the inner peripheral surface different from that in the other zone. SOLUTION: A cut part 1a is formed around the lower part of the pipe stock 1 and the pressure of high pressure water from a high pressure nozzle 3 is set to about 150-200 kgf/cm2 to completely wash out the cutting chip D generated at the time of boring by a cutting lathe in the cut part 1a. Because the zone except the cut part 1a of the inner peripheral surface of the pipe stock 1, where is a non-cut part (a), is soiled by the cutting oil or the like though the sticking quantity of the cutting chip D is small, the relative moving rate of the high pressure nozzle 3 in the vertical direction is controlled to be different in the zone except the cutting part 1a and in the zone of the cutting part 1a from each other.
