Hoʻokomo ʻia nā ʻāpana keleawe no nā kumu he nui.ʻO kekahi mau hopena i makemake nui ʻia ka hoʻomaikaʻi ʻana i ka ikaika tensile, ka paʻakikī, nā waiwai hopena, a me ka ductility.ʻO nā mea i hoʻokomo ʻia i ke keleawe e loaʻa i kahi kiʻekiʻe kiʻekiʻe.

ʻO nā kumu ʻē aʻe e koho ai nā mea kūʻai aku i ke komo ʻana i ke keleawe no ka hoʻomaikaʻi ʻana i ka ʻaʻahu a i ʻole ke kāohi ʻana i ke kahe o ka ea/gas ma kahi ʻāpana porous ʻē aʻe i nā mahana i hiki ʻole i ka resin ke hana.I kekahi manawa hoʻohana ʻia ka infiltration keleawe e hoʻomaikaʻi i nā ʻano machining o ke kila PM;waiho ka keleawe i ka hoʻopau mīkini ʻoi aku ka maʻalahi.

Eia ke ʻano o ka hana ʻana o ka copper infiltration:

ʻO ka ʻōnaehana kumu o ka ʻāpana i ʻike ʻia, i hoʻohana ʻia e hoʻoholo i ka nui o ka porosity hāmama.Ua koho ʻia ka nui o ke keleawe e like me ka nui o ka porosity e hoʻopiha ʻia.Hoʻopiha ke keleawe i ka porosity i ka wā o ka sintering (ma nā mahana ma luna o ka wela hoʻoheheʻe o ke keleawe) ma ke kau wale ʻana i ke keleawe i ka mea ma mua o ka sintering.ʻO ka> 2000 ° F sintering wela e hiki ai i ke keleawe hoʻoheheʻe ke kahe i loko o ka porosity mea ma o ka hana capillary.Hoʻopau ʻia ka sintering ma luna o ka mea lawe (e laʻa me ka pā seramika) no laila e paʻa ke keleawe ma ka ʻāpana.I ka manawa e maʻalili ai ka ʻāpana, hoʻopaʻa ʻia ke keleawe i loko o ka hale.
