Iwu uto nke agụụ evaporation mkpuchi ihe nkiri oyi akwa

N'oge mkpuchi evaporation, nucleation na uto nke ihe nkiri ihe nkiri bụ ihe ndabere nke teknụzụ mkpuchi ion dị iche iche

1.Nucleation

Inteknụzụ mkpuchi ikuku evaporation,mgbe film oyi akwa ahụ na- evaporated si evaporation isi iyi n'ụdị atọm, ha ofufe ozugbo na workpiece na elu agụụ na-etolite film oyi akwa site nucleation na ibu n'elu nke workpiece. N'oge ikuku evaporation, ike nke ihe nkiri oyi akwa atom na-agbanahụ na evaporation isi iyi bụ ihe dịka 0.2eV. Mgbe nchikota n'etiti irighiri ihe nke film oyi akwa dị ukwuu karịa bonding ike n'etiti atọm nke ihe nkiri oyi akwa na workpiece, na-etolite otu agwaetiti nucleus. Otu ihe nkiri oyi akwa atom na-anọ n'elu workpiece maka oge nke na-eme oge na-adịghị mma ije, mgbasa, Mbugharị, ma ọ bụ nkukota na ndị ọzọ atom na-etolite atọm ụyọkọ ọnụ ọgụgụ nke atọm na atomiki ụyọkọ rute a ụfọdụ oké egwu uru, a kwụsiri ike nucleus e guzobere, na-akpọ a homogeneous ekara oghere.

ire ụtọ, na nwere ọtụtụ ntụpọ na nzọụkwụ, nke na-akpata ọdịiche dị na adsorption ike nke akụkụ dị iche iche nke workpiece na redioaktivu atọm. Ike mgbasa ozi nke elu nke ntụpọ ahụ dị ukwuu karịa nke elu nkịtị, ya mere ọ na-aghọ ebe etiti na-arụ ọrụ, nke na-eme ka njedebe nke mmasị, nke a na-akpọ nucleation heterogeneous. Mgbe ike na-ejikọta ọnụ na-ejikọta ike na-ejikọta ya, ma ọ bụ ike na-ejikọta ya n'etiti akpụkpọ anụ akpụkpọ anụ na workpiece dị ukwuu karịa ike dị n'etiti akpụkpọ ahụ akpụkpọ ahụ, a na-emepụta usoro lamellar. Na teknụzụ plating ion, a na-emepụta isi agwaetiti n'ọtụtụ ọnọdụ.

2.Uto

Ozugbo isi nke ihe nkiri ahụ na-etolite, ọ na-aga n'ihu na-eto eto site na ọnyà ihe ahụ merenụ. Agwaetiti ahụ na-eto eto ma jikọta ya na ibe ya na-etolite nnukwu hemispheres, jiri nwayọọ nwayọọ na-akpụ akpụ n'àgwàetiti hemispherical nke na-agbasa n'elu nke workpiece.

Mgbe atomiki ike nke ihe nkiri oyi akwa dị elu, ọ nwere ike gbasaa zuru ezu n'elu na a ire ụtọ na-aga n'ihu film nwere ike kpụrụ mgbe ụdi na-abata atomiki ụyọkọ bụ small.If diffusion nke atọm n'elu bụ adịghị ike na size nke na-edebe ụyọkọ bụ nnukwu, ha na-adị dị ka nnukwu peninsular nuclei.The n'elu nke àgwàetiti ahụ nuclei akụkụ nke siri ike shadow mmetụta na-enwe mmetụta dị ike n'àgwàetiti "shadow isi na a conjuruted isi. mmetụta "Ntụle nke elu na-akawanye mma iji weghara atom ndị echekwabara na-esote na uto mmasị, na-ebute ogo concavity na-arịwanye elu n'elu iji mepụta kristal conical ma ọ bụ columnar nke zuru oke. A na-etolite oghere ndị na-abanye n'etiti kristal conical na uru ịdị nro dị elu na-abawanye. Enwere ike nweta anụ ahụ dị mma na oghere dị elu, na mbelata nke ogo agụụ, microstructure nke akpụkpọ ahụ na-aghọwanye ibu ma buru ibu.
