Hoʻolauna i nā ʻenehana maʻamau no ka waiho ʻana i nā uhi paʻa

1. ʻenehana Thermal CVD

ʻO nā uhi paʻa ka hapa nui o nā metala seramika (TiN, a me nā mea ʻē aʻe), i hana ʻia e ka hopena o ka metala i loko o ka uhi a me ka gasification reactive.I ka wā mua, ua hoʻohana ʻia ka ʻenehana CVD wela e hāʻawi i ka ikehu hoʻāla o ka hoʻohuihui ʻana e ka ikehu wela ma kahi wela kiʻekiʻe o 1000 ℃.He kūpono wale kēia mahana no ka waiho ʻana iā TiN a me nā mea hoʻopaʻa paʻa ʻē aʻe ma nā mea hana carbide cemented.A hiki i kēia manawa, he ʻenehana koʻikoʻi ia e waiho ai i nā uhi hoʻohuihui TiN-Al20 ma nā poʻo mea hana carbide cemented.

2. Hollow cathode ion coating a me ka uea wela arc ion coating

I ka makahiki 1980, ua hoʻohana ʻia ka hollow cathode ion coating a me ka uea wela arc ion coating no ka waiho ʻana i nā mea hana ʻoki.ʻO kēia mau ʻenehana hoʻoheheʻe ion ʻelua nā ʻenehana hoʻokuʻu ion coating, me ka helu ionization metala a hiki i 20% ~ 40%.

3. Ka uhi ʻana i ka ion cathode arc

ʻO ka puka ʻana o ka cathodic arc ion coating i alakaʻi i ka hoʻomohala ʻana i ka ʻenehana o ka waiho ʻana i nā pale paʻakikī ma nā mold.ʻO ka nui o ka ionization o ka cathodic arc ion coating he 60% ~ 90%, e ʻae ana i ka nui o nā ion metala a me nā kinoea hopena e hiki i ka ʻili o ka mea hana a mālama mau i ka hana kiʻekiʻe, e hopena i ka hoʻopiʻi ʻana a me ka hoʻokumu ʻana o nā uhi paʻakikī e like me TiN.I kēia manawa, hoʻohana nui ʻia ka ʻenehana cathodic arc ion coating no ka waiho ʻana i nā uhi paʻakikī ma nā mold.

ʻO ke kumu cathode arc he kumu hoʻoheheʻe ʻia me ka ʻole o ka wai hoʻoheheʻe paʻa, a hiki ke kau ʻia ke kumu kumu arc, e hoʻomaikaʻi i ka nui o ka hoʻohana ʻana i ka lumi o ka lumi uhi a hoʻonui i ka hiki ke hoʻouka i ka umu.ʻO nā ʻano o nā kumu arc cathode e komo pū me nā kumu arc cathode pōʻai liʻiliʻi, nā kumu arc columnar, a me nā kumu arc ākea pālahalaha ʻehā.Hiki ke hoʻonohonoho kaʻawale ʻia nā ʻāpana like ʻole o nā kumu arc liʻiliʻi, nā kumu arc columnar, a me nā kumu arc nui e waiho i nā kiʻiʻoniʻoni multi-layer a me nā kiʻiʻoniʻoni nano multilayer.I kēia manawa, ma muli o ke kiʻekiʻe o ka ionization metala kiʻekiʻe o ka cathodic arc ion coating, hiki i nā ion metala ke komo i nā kinoea hoʻololi hou aʻe, e hopena i kahi ākea kaʻina hana a me ka hana maʻalahi e loaʻa ai nā pale paʻakikī maikaʻi loa.Eia nō naʻe, aia nā kulu koʻikoʻi i loko o ka microstructure o ka papa uhi i loaʻa e ka cathodic arc ion coating.I nā makahiki i hala iho nei, ua puka mai nā ʻenehana hou e hoʻomaʻemaʻe i ke ʻano o ka papa kiʻiʻoniʻoni, kahi i hoʻomaikaʻi ai i ka maikaʻi o ke kiʻi ʻoniʻoni arc ion coating.
