Nā waiwai a me nā noi o nā kiʻi daimana mokuna 1

ʻO ka daimana i hoʻokumu ʻia me ka hoʻopaʻa ʻana i nā kemika ikaika loaʻa nā waiwai mechanical a me nā elastic. ʻO ka paʻakikī, ka nui a me ka thermal conductivity o ke daimana ka mea kiʻekiʻe loa ma waena o nā mea i ʻike ʻia. Loaʻa iā Diamond ka modulus kiʻekiʻe o ka elasticity o kekahi mea. ʻO 0.05 wale nō ke koena o ka friction o kahi kiʻi daimana. Eia kekahi, ʻo ka daimana ka mea kiʻekiʻe loa o ka thermal conductivity, e piʻi aʻe ma kahi helu ʻoi aku ma mua o ʻelima inā hoʻomākaukau ʻia ke kiʻi daimana me ka hoʻohana ʻana i nā isotopes maʻemaʻe o ke kalapona. ʻO ke kumu nui o ka hoʻohana ʻana i nā isotopes o ke kalapona no ka hoʻomākaukau ʻana i ke daimana e hōʻemi i ka hoʻopuehu phonon o daimana. Ma ke ʻano he mea superhard, ʻo ke kiʻi daimana he mea hoʻonaninani maikaʻi, hiki ke uhi ʻia ma ka ʻili o nā mea hana ʻoki a me nā mold e hoʻomaikaʻi nui ai i ko lākou ʻili a hoʻonui i ko lākou ola lawelawe. Hiki ke hoʻohana ʻia ka coefficient haʻahaʻa o ka friction a me ka conductivity thermal kiʻekiʻe o nā kiʻi daimana no nā bearings kiʻekiʻe no ka huaʻōlelo lele. ʻO ka conductivity thermal kiʻekiʻe, ka haʻahaʻa haʻahaʻa o ka friction a me ka transmittance māmā maikaʻi o ke kiʻi daimana e hoʻohana pinepine ʻia e like me ka fairing material o nā missiles.

(2) Nā Waiwai Thermal a me nā hoʻohana ʻana o Diamond
I kēia mau lā, kokoke loa ka conductivity thermal o ke kiʻi daimana synthetic i ka daimana maoli. Ma muli o kona kiʻekiʻe thermal conductivity a kiʻekiʻe uila resistivity, daimana hiki ke hoʻohana 'ia e like me ka insulating papa o integrated kaapuni substrate, a me ka thermally conductive insulating papa o paʻa-moku'āina lasers. Eia kekahi, ʻo ka conductivity thermal kiʻekiʻe o daimana, liʻiliʻi ka wela wela, ʻoi aku hoʻi i nā wela kiʻekiʻe ke koʻikoʻi ka hopena o ka wela, he mea wela maikaʻi loa. Me ka hoʻomohala ʻana i ka ʻenehana deposition kiʻiʻoniʻoni kiʻekiʻe thermal conductivity, ua hana ʻo ia i ka noi ʻana o ke daimana thin film thermal deposition ma luna o nā lasers mana kiʻekiʻe, nā mīkini microwave a me nā kaapuni i hoʻohui ʻia.
Eia nō naʻe, ʻokoʻa nā waiwai o nā kiʻi daimana artificial ma muli o nā kaʻina hoʻomākaukau like ʻole. No ka laʻana, nā waiwai lawe wela, i ʻike nui ʻia e nā ʻokoʻa nui o ka diffusivity thermal a me ka conductivity thermal. Eia kekahi, hōʻike ka anisotropy ikaika i ke kiʻi daimana hana, a ʻoi aku ka liʻiliʻi o ka conductivity thermal o ka mānoanoa kiʻi like like me ka ili kiʻiʻoniʻoni. Hoʻokumu ʻia kēia ma muli o nā ʻāpana hoʻomalu like ʻole i ke kaʻina hana kiʻiʻoniʻoni. Hiki ke ʻike ʻia he pono e hoʻomaikaʻi hou ʻia ka hana hoʻomākaukau ʻana o nā kiʻi ʻoniʻoni lahilahi daimana i mea e hoʻohana nui ʻia ai kāna hana maikaʻi.
