O le maualuga o le mamafa o le masini YN52S00027P1 e talafeagai mo SK200-6 excavator o Shengang

◆ Mo mea e faʻaaogaina i vaʻa eletise maualuga, togafitiga vevela ma le faʻamaʻaina o luga e masani ona faʻaaogaina e faʻaleleia atili ai le faʻafefeteina ma le faʻafefe.

1, vacuum vevela togafitiga

Vacuum vevela togafitiga e faasino i le faagasologa o togafitiga vevela lea e tuu ai le mea faigaluega i le masini. O togafitiga vevela vevela e le maua ai le faʻamaʻiina, decarburization ma isi faʻamaʻi i le taimi o le faʻamafanafanaina, ae o loʻo i ai foi le galuega o le faʻamamāina o luga, faʻafefe ma degreasing. O le hydrogen, nitrogen ma le okesene e faʻaaogaina e meafaitino i le taimi o le faʻafefeteina e mafai ona aveese i le vacuum, ma e mafai ona faʻaleleia le lelei ma le faʻatinoga o mea. Mo se faʻataʻitaʻiga, i le maeʻa ai o togafitiga vevela vevela o le valve nilala maualuga maualuga e faia i le W18Cr4V, o le aʻafiaga o le faʻaogaina o le tui o le nila e faʻaleleia lelei, ma i le taimi lava e tasi, o mea faʻainisinia ma le ola tautua e faʻaleleia.

2. Fa'asagaga fa'amalosi i luga

Ina ia faʻaleleia atili le faʻatinoga o vaega, faʻaopoopo i le suia o meafaitino, e sili atu le faʻamalosia o metotia togafitiga faʻaogaina. E pei o le tineia luga (faavevela afi, maualuga ma le feololo faʻavevela faʻavevela luga tineia, faʻafesoʻotaʻi faʻavevela eletise faʻavevela luga, faʻafefeteina faʻavevela eletise eletise, faʻavevela eletise eletise eletise eletise, ma isi), carburizing, nitriding, cyaniding, boronizing (TD method), faʻamalosia leisa, faʻamalo ausa vailaʻau (Metotia CVD), faʻapipiʻi ausa faaletino (Metotia PVD), faʻapipiʻi vailaʻau vailaʻau plasma (Metotia PCVD) faʻapipiʻi plasma, ma isi.

Fa'ate'aina ausa fa'aletino (Meto'a PVD)

I totonu o le vacuum, o metotia faʻaletino e pei o le faʻasao, faʻapipiʻiina o le ion ma le sputtering e faʻaaogaina e gaosia ai ion uʻamea. O nei u'amea u'amea o lo'o teuina i luga o le mea faigaluega e fai ai se u'amea u'amea, po'o le tali atu i le reactor e fausia ai se fa'aputu fa'afefiloi. O lenei faiga o togafitiga e ta'ua o le fa'a'afu tino, po'o le PVD mo se fa'apuupuu. O lenei metotia o loʻo i ai le lelei o le maualalo o le vevela vevela, 400 ~ 600 ℃ vevela togafitiga, faʻaletonu laiti ma sina aʻafiaga i le fausaga matrix ma meatotino o vaega. O se vaega o le TiN na teuina i luga o le tui nila na faia i le W18Cr4V e ala ile PVD. O le TiN layer e matua maualuga lava le maaa (2500 ~ 3000HV) ma le maualuga o le ofuina, e faʻaleleia ai le faʻafefe o le valve, e le pala i le faʻafefeteina o le hydrochloric acid, sulfuric acid ma le nitric acid, ma e mafai ona faʻatumauina le susulu. A maeʻa togafitiga PVD, e lelei le saʻo o le ufiufi. E mafai ona palapala ma fa'aiila, ma o lona mata'utia o luga o le Ra0.8µm, lea e mafai ona o'o i le 0.01µm pe a uma ona fa'aiila.
