用仿金刚石碳精粉涂层提高喷射织机钢筘的耐磨性

喷射织机钢筘的磨损问题，直接影响到织机效率、织物品质、生产成本一直是纺器和织造业关注的热点，本文介绍日本用仿金刚石石炭精粉涂层，使筘齿的硬度量值超过２０００以上，用加速试验机作磨损试验，证明其耐磨性比没有涂层的上同筘齿原料，提高了１００倍以上。所以，这种涂层技术的应用交圾益于纺器和织造业。     

Preparation and Properties of Sintering Additives Coated Si3N4 from Heterogeneous Nucleation Processing

The sintering additives such as Al2O3 and /or Y2O3 were coated on the surfaces of Si3N4 particles via heterogeneous nucleation processing using a buffered pH solution as the precipitation reagent .They nucleated and grew only on the surfaces of Si3N4 and did not form sol particles in solution by TEM observation .The isoelectric point(IEP) of coated Si3N4 was different from that of as-received Si3N4.The IEP of Al(OH)3-coated Si3N4 occurred at pH8.4, which is close to that of alumina .When Al(OH)3-coated Si3N4 particles were coated with Y(OH)3,the IEP of coated Si3N4 powder shifted from pH8.4 to pH9.2 ,similar to that of yttria.In addition ,the rheological data showed that Al2O3 and /or Y2O3 coated Si3N4 suspension is nearly Newtonian and that added Si3N4 suspension shows a shear rate thinning behavior.
