He aha ka ʻenehana uhi PVD

ʻO ka uhi ʻana o PVD kekahi o nā ʻenehana nui no ka hoʻomākaukau ʻana i nā mea ʻili lahilahi

Hāʻawi ka papa ʻoniʻoni i ka ʻili o ka huahana me ke ʻano metala a me ke kala momona, hoʻomaikaʻi i ke kūpaʻa ʻana i ka ʻaʻahu a me ke kūpaʻa ʻana i ka corrosion, a hoʻolōʻihi i ke ola lawelawe.

ʻO ka sputtering a me ka vacuum evaporation nā ʻano hana uhi PVD kaulana loa.

1. Wehewehena

ʻO ke ʻano o ka hoʻomoe ʻana i ka mahu kino he ʻano ia o ka ulu ʻana o ka hopena mahu kino. Hana ʻia ke kaʻina hana hoʻomoe ma lalo o ka vacuum a i ʻole nā ​​kūlana hoʻokuʻu kinoea haʻahaʻa, ʻo ia hoʻi, ma ka plasma haʻahaʻa.

ʻO ke kumu o ka uhi ʻana, he mea paʻa ia. Ma hope o ka "moho ʻana a i ʻole ka pīpī ʻana", e hana ʻia kahi uhi mea paʻa hou ʻokoʻa loa mai ka hana o ka mea kumu ma luna o ka ʻili o ka ʻāpana.

2, Ke kaʻina hana kumu o ka uhi ʻana o PVD

1. Ka hoʻokuʻu ʻia ʻana o nā ʻāpana mai nā mea maka (ma o ka evaporation, sublimation, sputtering a me ka decomposition);

2. Hoʻoili ʻia nā ʻāpana i ka substrate (kuʻi nā ʻāpana kekahi i kekahi, e hopena ana i ka ionization, recombination, reaction, exchange ikehu a me ka loli o ke kuhikuhi neʻe);

3. Hoʻopili nā ʻāpana, hoʻopili i ka nucleate, ulu a hana i kahi ʻili ma luna o ka substrate.
