When paalubricantsHoʻohui ʻia i loko o ka metala a i ʻole ka matrix seramika ma ke ʻano he ʻāpana no ka sintering element hui, pili nā waiwai tribological i ka ua a me ka puʻu ʻana o nā lubricants paʻa i ka matrix i ka wā o ka friction.
HEia naʻe, nalo nā lubricants paʻa i ka ʻāpana o ko lākou lubricity ma muli o ka oxidation a me ke ahi i ka wā o ka sintering i ka wela kiʻekiʻe.I ka manawa like, ʻo ka inhomogeneity o ka hāʻawi ʻana i ka lubricant paʻa a me kona pōʻino i ka hoʻomau ʻana o ka matrix e hōʻemi nui i ka ikaika, ka paʻakikī a me ka pale ʻana o nā composites.
TʻO ke ala kūpono ʻo ia ka hoʻoheheʻe ʻana i ka lubricant paʻa i hoʻoheheʻe ʻia i loko o ka microporous through-through preform, e hana ana i ka infiltration compound kiʻekiʻe kiʻekiʻe kiʻekiʻe lubricating mea me ka ʻoihana pūnaewele ma o ka matrix paʻakikī a me ka papa lubrication palupalu.
