Abstract In this research for first time attempt to produce mechanical seal by selfpropagation high temperature synthesis method SHS Therefore investigatepossibility of produce TiC TiB2 TiC SiC Ti3SiC2 TiC TiB2 SiC TiC NiAl andTiB Ti composit by SHS method Then with using of scaning electron microscope SEM energy dispersive spectrometr EDS and X ray diffraction XRD distinguishconstructed phases With attention to this point that the most mechanical seal is from silicon carbidecompound therefore attempt to compare tribological properties of producted samplesby SHS method with SiC sample produced by sintering method between of productedsix sample TiB Ti and TiC NiAl samples have close properties with sic sample forexample hardness and decreasing weight in wear test With attention to positive result of TiB Ti and TiC NiAl samples in contrast ofsic sample provided mechanical seal gasket of this samples and put in afew pump fordoing endorable test Microscopic observations showes that the mechanism wear inTiB Ti is adhesive SiC and TiC NiAl abrasion adhesion and tribochimical and inother sample abrasive have be in pin on disk wear test Likewise For mechanical sealin working condition the mechanismes of wear are abrasion adhesion tribochimicaland corrosion wear For evaluation corrosion did immersion test for TiB Ti and TiC NiAl Samples Resultes showes suitable resistant of this compound in acid and causticenvironmentes Collection of resultes showes that with SHS method can produce propercompound of mechanical seal gasket for application in various fluides asid andcaustic solutions
