Popanga zida zodulira za carbide zodulira zida zamafuta (zomwe zimagwiritsidwa ntchito podulira zida monga nayiloni, poliyesitala, ndi kaboni fiber), njirayi ndi yovuta, yomwe imaphatikizapo njira zingapo zofunika kuphatikiza kusankha zinthu, kupanga, sintering, ndi kukonza m'mphepete. Gawo lililonse lingakhale ndi zovuta zaukadaulo. Pansipa pali Mavuto akulu omwe amakumana nawo panthawi yopanga ndi mayankho awo.
I. Zovuta pa Gawo Lokonzekera Zinthu
1. Homogeneity yosakwanira ya WC-Co Powder
Vuto likhoza kukhala:
Kusakaniza kosafanana kwa ufa wa cemented carbide (WC-Co) kumapangitsa kuti pakhale tsankho pambuyo poti sintering, kusokoneza kulimba-kulimba mtima.
Mayankho kwa inu:
Konzani homogeneity ya ufa pogwiritsa ntchito mphero yamagetsi yamphamvu kwambiri kapena kuyanika kwautsi.
Onjezani trace grain growth inhibitors (mwachitsanzo, Cr₃C₂, VC) kuti muwongolere kukula kwa mbewu za WC (0.5–1 μm).
2. Kugawa Kosagwirizana kwa Binder Phase (Co)
Vuto likhoza kukhala:
Co-phase aggregation imapanga "madziwe a cobalt," amachepetsa kukana kwamphamvu ndikupangitsa kuti m'mphepete mudulidwe ulusi.
Zomwe tingachite:
Gwiritsani ntchito ufa wa nano-cobalt (<100 nm) wokhala ndi mphero yonyowa kuti muwonjezere kubalalitsidwa.
Sinthani kutentha kwa sintering (sungani 1400-1450 ° C panthawi ya sintering yamadzimadzi).
II. Zovuta Zopanga ndi Kupanga Sintering
1. Zolakwika mu Press Kupanga
Vuto likhoza kukhala:
Kachulukidwe inhomogeneity pa ozizira isostatic kukanikiza (CIP) kapena kufa kukanikiza kumayambitsa ming'alu / delamination matupi obiriwira.
Mayankho kwa inu:
Konzani kukakamiza kukanikiza (200-300 MPa) ndikukhala nthawi.
Adopt bidirectional pressing kapena metal injection molding (MIM) ya ma geometries ovuta.
2. Sintering Deformation ndi Dimensional Instability
Vuto likhoza kukhala:
Kutsika kosasunthika kwa sintering (nthawi zambiri 15-20%) kumabweretsa kupatuka kwambiri kwa geometry m'mphepete (mwachitsanzo, m'mphepete mwake> 10 μm).
Njira Zowongolera:
Gwiritsani ntchito ma graphite molds + Al₂O₃ spacers kuti muchepetse kutentha kwambiri.
Gwiritsani ntchito spark plasma sintering (SPS) kuti muchepetse nthawi ya sintering ndi porosity (<0.5%).
III. Kukonza M'mphepete ndi Zovuta Zopaka
1. Ultra-Precision Mphepete Akupera Zovuta
Vuto likhoza kukhala:
Kupeza m'mphepete lakuthwa (m'mphepete mwa radius <5 μm) kumalepheretsedwa ndi kuuma kwakukulu (HRA ≥90), kuchititsa kutsika kocheperako komanso kuvala magudumu mwachangu.
Kukhathamiritsa kwa Njira:
Gwiritsani ntchito mawilo a diamondi (kukula kwa grit W10-W20) okhala ndi ma electrolytic in-process dressing (ELID).
Adopt laser-assisted grinding (LAG) kuti muchepetse mphamvu yopera ndikuwongolera roughness pamwamba (Ra ≤0.1 μm).
2. Osakwanira ❖ kuyanika Adhesion
Vuto likhoza kukhala:
Zovala za TiAlN/DLC zimachoka panthawi yodula kwambiri ulusi wopangidwa (makamaka utomoni wopangidwa ndi kaboni).
Njira Zowonjezera:
Kuchiza: Ar⁺ ion bombardment kuyeretsa + Cr interlayer (0.2–0.5 μm thick).
Sinthani ku zokutira zamitundu yambiri (mwachitsanzo, TiCN/AlTiO₃), kukonza zomatira ndi> 30%.

Nthawi zambiri T/T, Western Union... deposits firstm, Maoda onse oyamba kuchokera kwa makasitomala atsopano amalipidwa. Maoda ena atha kulipidwa ndi invoice...Lumikizanani nafekudziwa zambiri
Inde, tiuzeni, Mipeni Yamafakitale imapezeka m'mitundu yosiyanasiyana, kuphatikiza mbale zapamwamba, mipeni yozungulira pansi, mipeni ya serrated / mano, mipeni yozungulira, mipeni yowongoka, mipeni ya guillotine, mipeni yosongoka, lumo lamakona anayi, ndi masamba a trapezoidal.
Kukuthandizani kuti mupeze tsamba labwino kwambiri, Huaxin Cement Carbide ikhoza kukupatsani masamba angapo kuti muyese kupanga. Podulira ndikusintha zida zosinthika monga filimu yapulasitiki, zojambulazo, vinyl, mapepala, ndi zina, timapereka masamba otembenuza kuphatikiza ma slitter ndi malezala okhala ndi mipata itatu. Titumizireni funso ngati mukufuna makina amakina, ndipo tikupatseni mwayi. Zitsanzo za mipeni yopangidwa mwamakonda sizipezeka koma ndinu olandiridwa kuti muyitanitsa kuchuluka kwa madongosolo ocheperako.
Pali njira zambiri zomwe zingatalikitse moyo wautali komanso alumali wamipeni yanu yamakampani ndi masamba omwe ali mgululi. tiuzeni kuti mudziwe momwe kuyika bwino kwa mipeni yamakina, malo osungira, chinyezi ndi kutentha kwa mpweya, ndi zokutira zowonjezera zidzateteza mipeni yanu ndikusunga ntchito yawo yodula.
