Indlela yokukhetha izixhobo zokucofa kunye neengubo?

Xa sicofa imisonto, zininzi iintlobo zeempompo onokuthi ukhethe kuzo.Sinokuzikhetha njani?Njengeukucofa intsimbi eqinile, ukucofa intsimbi, okanye ukucofa ialuminiyam, kufuneka senze njani?

1. Intsimbi yesantya esiphezulu: Okwangoku isetyenziswa ngokubanzi njengempompo, njenge-M2 (W6Mo5Cr4V2, 6542), i-M3, njl., siyibiza ngokuba yi-HSS.

2. Intsimbi ye-Cobalt enesantya esiphezulu: Okwangoku isetyenziswa ngokubanzi njengemathiriyeli yempompo, njenge-M35, M42, njl., ebizwa ngokuba yi-HSS-E.

3. I-powder metallurgy high-speed steel: isetyenziswe njengesixhobo sempompo ephezulu yokusebenza, ukusebenza kwayo kuphuculwe kakhulu xa kuthelekiswa nezi zimbini zingasentla, kwaye iindlela zokuqamba zomenzi ngamnye nazo ziyahluka, kunye nekhowudi yokumakisha i-HSS-E-PM. .

4. I-Tungsten carbide: ihlala ikhetha ibakala le-ultrafine le-carbide, elisetyenziselwa ukuvelisa impompo yeflute ethe tye, enjengeempompo ze-carbide zentsimbi engwevu, iimpompo ze-carbide zentsimbi eqinile,itephu ye-carbide ye-aluminium, njl., siyibiza ngokuba ziimpompo ze-carbide.

Imisonto yokutephu

bathembele kakhulu kwimathiriyeli, kwaye ukukhetha imathiriyeli elungileyo kunokwandisa ngakumbi iiparamitha zesakhiwo sempompo, iyenze ilungele iimeko zokusebenza ezisebenzayo nezifuna kakhulu, ngelixa ikwanobomi obude.

Ukwaleka itephu

1. I-Steam oxidation: Itephu ibekwe kumphunga wamanzi wobushushu obuphezulu ukwenza umaleko wefilimu ye-oxide kumphezulu wayo, ene-adsorption elungileyo kwisipholisi kwaye inokunciphisa ukukhuhlana, ngelixa ikhusela ukunamathela phakathi kwempompo kunye nezinto ezisikwayo.Ilungele ukusetyenzwa kwentsimbi ethambileyo.

2. Unyango lwe-nitriding: Umphezulu wempompo ufakwe i-nitrided ukwenza i-surface layering layer, ifanelekile kwizinto zokucubungula ezifana nentsimbi kunye ne-aluminium ephosiweyo enokumelana okuphezulu kwezixhobo zokusika.

3. I-TiN: Ingubo yegolide etyheli, enobulukhuni obuhle bokugquma kunye nokuthambisa, kunye nokusebenza kakuhle kokuncamathisela, ilungele ukusetyenzwa kwezinto ezininzi.

4. I-TiCN: I-Blue grey coating, kunye nobunzima obumalunga ne-3000HV kunye nokumelana nobushushu ukuya kuma-400 ° C.

5. I-TiN + TiCN: Iingubo ezinzulu ezityheli ezinobunzima obubalaseleyo bokugquma kunye nokuthambisa, zilungele ukusetyenzwa uninzi lwezixhobo.

6. I-TiAlN: I-blue grey coating, ubunzima be-3300HV, ukumelana nobushushu ukuya kwi-900 ° C, ifanelekile kwi-high-speed machining.

7. I-CrN: I-Silver grey coating kunye nokusebenza okugqwesileyo kokuthanjiswa, ngokukodwa kusetyenziselwa ukusetyenzwa kweentsimbi ezingenayo i-ferrous.
