水潤滑下におけるステンレス鋼と各種樹脂材料の線接触しゅう動特性

This paper aims to provide data of friction and wear characteristics under water lubricated sliding conditions between polymer and stainless steel in order to help develop water lubrication systems. The tests were carried out using block on ring friction testing machine (FALEX LFW-1), so the results described in this paper are obtained under line contact and pure slip in one direction continuous sliding condition. The materials of block specimens are crystalline engineering plastics and they are PEEK(Poly Ether Ether Ketone), PPS(Poly Phenylene Sulfide), POM(Poly Oxy Methylene), PBT(Poly Butylene Terephthalate) and UHMWPE(Ultra High Molecular Weight Polyethylene). The results show the material which had higher friction coefficient also had high specific wear rate. This tendency largely depends on the hardness and the heat resistant temperature. A soft material such as UHMWPE had low friction coefficient and specific wear rate, but it was confirmed that the surface is roughened, which is remarkable when tested at a temperature close to the heat resistant temperature.
