Optimization of pretreatment schemes for electroless nickel plating of three solid lubricants
Since there is no circulating medium to cool bits and clear drilling cuttings in the lunar drilling environment, the diamond coring bit is required to have good self-lubricating performance. Adding electroless nickel plated solid lubricants to the bit matrix can solve this problem efficiently, and reinforce the mechanical properties of the self-lubricated bit matrix at the same time. In this paper, two pretreatment schemes were designed according to three typical solid lubricants (i.e. MoS2, WS2, and CaF2), and the optimal pretreatment scheme suits for each solid lubricant were obtained by systematic tests. The test results show that the pretreatment scheme of electroless nickel plating has different effects on the three solid lubricants. During the roughening process, the introduce of sodium dodecyl sulfate (SDS) will produce more dense and uniform pits on the surface of CaF2, while that of SDS on the roughening process of MoS2 is leading to the rupture and disintegration of MoS2. Besides, WS2 will be oxidized to WO3 during the roughening process, so the roughening process should be avoid for WS2.
期刊介绍:
Wear journal is dedicated to the advancement of basic and applied knowledge concerning the nature of wear of materials. Broadly, topics of interest range from development of fundamental understanding of the mechanisms of wear to innovative solutions to practical engineering problems. Authors of experimental studies are expected to comment on the repeatability of the data, and whenever possible, conduct multiple measurements under similar testing conditions. Further, Wear embraces the highest standards of professional ethics, and the detection of matching content, either in written or graphical form, from other publications by the current authors or by others, may result in rejection.
