Phello ea phekolo ea ho roala holim'a taemane

1. Khopolo ea ho roala holim'a taemane

Ho roala ka holim'a daemane, ho bolela tšebeliso ea thekenoloji ea kalafo holim'a holim'a taemane e koahetsoeng ka lera la filimi ea thepa e 'ngoe. E le thepa ea ho roala, hangata tšepe (ho akarelletsa le motsoako), joalo ka koporo, nickel, titanium, molybdenum, koporo tin titanium motsoako, nickel cobalt motsoako, nickel cobalt phosphorus motsoako, joalo-joalo; thepa ea ho roala le lisebelisoa tse ling tseo e seng tsa tšepe, joalo ka lirafshoa, titanium carbide, titanium ammonia le metsoako e meng ea thepa e thata ea refractory. Ha thepa ea ho roala e le tšepe, e ka boela ea bitsoa diamond surface metalation.

Morero oa ho roala holim'a metsi ke ho fa likaroloana tsa daemane ka thepa e khethehileng ea 'mele le ea lik'hemik'hale, e le ho ntlafatsa ts'ebeliso ea tsona. Mohlala, ts'ebeliso ea lebili le silang la daemane le koahetsoeng ka holim'a metsi, bophelo ba eona ba ts'ebeletso bo atolosoa haholo.

2. Khethollo ea mokhoa oa ho roala holim'a metsi

Indasteri holim'a mekhoa ea phekolo ea mekhoa ea ho hlopha bona palo e ka tlase, e hlileng e sebelisitsoeng ka mokhoa o thata oa ho roala holim'a metsi, o tsebahalang haholo ke ho roala lik'hemik'hale tse metsi (ha ho na electrolysis plating) le plating, plating e omileng (eo hape e tsejoang e le vacuum plating) ka lik'hemik'hale tsa mouoane oa lik'hemik'hale (CVD) le mouoane oa 'mele (PVD), ho kenyelletsa le mokhoa o sebetsang oa vacuum powder.

 

3. Plating botenya emela mokhoa

Hobane botenya ba ho roala holim'a likaroloana tsa abrasive tsa daemane ho thata ho tseba ka ho toba, hangata ho hlalosoa e le boima ba 'mele (%). Ho na le mekhoa e 'meli ea ho eketsa boima ba' mele:

Moo A ke phaello ea boima (%); G1 ke boima ba ho sila pele ho plating; G2 ke boima ba ho roala; G ke boima ba kakaretso (G=G1 + G2)

4. Phello ea ho roala holim'a taemane holim'a ts'ebetso ea sesebelisoa sa daemane

Ka sesebelisoa sa daemane se entsoeng ka Fe, Cu, Co le Ni, likaroloana tsa daemane li ka kenngoa ka mochine ka har'a matrix ea moemeli ea tlamang ka lebaka la ho se kopane ha lik'hemik'hale tsa moemeli ea tlamang ka holimo le ho haelloa ke ho kenella ha sebopeho. Tlas'a ketso ea matla a ho sila, ha karoloana ea ho sila ea daemane e pepesehetse karolong e phahameng ka ho fetisisa, tšepe ea 'mele oa thaere e tla lahleheloa ke likaroloana tsa daemane ebe e oela ka boeona, e leng ho fokotsang bophelo ba tšebeletso le ho sebetsa hantle ha lisebelisoa tsa daemane,' me phello ea ho sila ea daemane e ke ke ea bapaloa ka botlalo. Ka hona, bokaholimo ba daemane bo na le litšobotsi tsa metallization, tse ka ntlafatsang bophelo ba ts'ebeletso ka katleho le ho sebetsa hantle ha lisebelisoa tsa daemane. Ntho ea bohlokoa ea eona ke ho etsa lintho tse tlamang tse kang Ti kapa alloy ea eona e koahetsoeng ka ho toba holim'a daemane, ka ho futhumatsa le ho futhumatsa phekolo, e le hore holim'a taemane e thehe lesela le ts'oanang la lik'hemik'hale tsa lik'hemik'hale.
Ka ho roala daemane ho sila likaroloana, karabelo ea barbotage le daemane ho metalize holim'a taemane. Ka lehlakoreng le leng, metallized daemane holim'a le tšepe 'mele tlama moemeli pakeng tsa tšepe metallurgical motsoako, ka hona, barbotage kalafo ea taemane bakeng sa batang khatello mokelikeli sintering le ho chesa tiileng mohato sintering na le applicability e pharaletseng, kahoo thaere motsoako motsoako bakeng sa daemane sila lijo-thollo consolidation e eketseha, fokotsa sesebelisoa sa taemane ha ho sebelisoa ho sila, ho ntlafatsa bophelo ba tšebeletso le katleho ea lisebelisoa tsa daemane.

5. Mesebetsi e ka sehloohong ea phekolo ea ho roala taemane ke efe?

1. Ntlafatsa bokhoni ba 'mele oa fetal ho kenya taemane.
Ka lebaka la ho hola ha mocheso le ho honyela ha serame, khatello e matla ea mocheso e hlahisoa sebakeng sa ho kopana lipakeng tsa daemane le 'mele oa thaere, e leng se tla etsa hore daemane le lebanta la lesea la fetal le hlahise mela e menyane, ka hona, ho fokotsa bokhoni ba thaere e koahetsoeng ka daemane. Ea taemane holim 'a barbotage ka ntlafatsa thepa ea' mele le lik'hemik'hale tsa daemane le 'mele segokanyimmediamentsi sa sebolokigolo, ka ho hlahloba matla manyenyane, o ile a tiisa hore tšepe carbide sebopeho ka filimi ho tloha ka hare ho ka ntle butle-butle phetoho ho likarolo tšepe, bitsoa MeC-Me filimi, holim'a taemane le filimi ke tlamo ea lik'hemik'hale, motsoako ona feela o ka ntlafatsa bond bokhoni ba daemane, kapa ntlafatsa bokhoni ba thaere 'mele oa daemane. Ke ho re, coating e sebetsa e le borokho bo tlamang pakeng tsa tse peli.
2. Ntlafatsa matla a taemane.
Hobane likristale tsa daemane hangata li na le bofokoli ba ka hare, joalo ka li-microcracks, li-cavities tse nyane, joalo-joalo, liphoso tsena tse kahare ho likristale li lefelloa ka ho tlatsa lera la MeC-Me. Plating e phetha karolo ea ho matlafatsa le ho tiisa. Ho roala lik'hemik'hale le ho roala li ka ntlafatsa matla a lihlahisoa tse tlaase, tse mahareng le tse phahameng.
3. Fokotsa mocheso oa mocheso.
Ho roala ka tšepe ho lieha ho feta ha daemane ea abrasive. Mocheso oa ho sila o fetisetsoa ho moemeli ea tlamang resin ha o kopana le karoloana ea ho sila, e le hore e chesoe ho tloha ts'ebetsong ea mocheso o phahameng hang-hang, e le ho boloka matla a eona a ho tšoara holim'a daemane abrasive.
4. Ho itšehla thajana le phello ea tšireletso.
Nakong ea mocheso o phahameng oa sintering le ho sila ka mocheso o phahameng, lesela la ho roala le arola le ho sireletsa daemane ho thibela graphitization, oxidation kapa liphetoho tse ling tsa lik'hemik'hale.
