Njira yanji Powder metallurgy sintering

Ufa zitsuloamapangidwa ndi kupanga ufa, kukanikiza akamaumba,kuimba, ndi post-processing, ndi sintering ndi imodzi mwa njira zofunika za ufa zitsulo. Pa zitsulo ufa sintering ndondomeko, ufa particles ayenera kuyenda, diffuse, kusungunuka, recrystallize ndi zina thupi ndi mankhwala. Njirayi imawonjezeranso ufa ndikuchotsa zina kapena ma pores ake onse. Palinso njira zingapo zopangira sintering ufa wa metallurgy sintering. Ndiye, zomwe zimagwiritsidwa ntchito kwambirinjira zowerengeraza zitsulo za ufa?

Njira zopangira zitsulo za ufa nthawi zambiri zimagwera m'magulu awa:

1. Gawo lamadzimadzi sintering

Ngati pali zigawo ziwiri kapena zingapo mu ufa yaying'ono, sintering akhoza kuchitidwa pamwamba pa malo osungunuka a chigawo china, kotero pang'ono madzi gawo limapezeka mu ufa yaying'ono pa sintering.

2. Pressure sintering

Panthawi ya zitsulo za ufa, kukakamiza kumagwiritsidwa ntchito pa thupi la ufa kuti lipititse patsogolo kachulukidwe kake. Pressure sintering nthawi zina amafanana ndi kukanikiza kotentha, yomwe ndi njira yomwe imaphatikiza kupanga ndi kupukuta kwa ufa kuti upeze mwachindunji magawo a sintering.

3. Kuyambitsa sintering

Miyezo ina yakuthupi kapena yamankhwala imatengedwa munjira ya sintering, kotero kuti kutentha kwa sintering kumachepetsedwa kwambiri, nthawi ya sintering imafupikitsidwa kwambiri, ndipo magwiridwe antchito a sintered amawongolera ndikuwongolera.

4. EDM sintering

Pamene thupi la ufa limapangidwa ndikukanikizidwa, magetsi olunjika komanso othamanga amagwiritsidwa ntchito kuti apange arc pakati pa tinthu tating'ono tomwe timatulutsa sintering; panthawi ya mim sintering, kupanikizika kumagwiritsidwa ntchito pang'onopang'ono ku workpiece, ndipo njira ziwiri zopangira ndi sintering zimaphatikizidwa.

5. Ufa olimba gawo sintering

Njira yopangira ufa yomwe ufa wosasunthika kapena zophatikizika sizisungunuka panthawi ya sintering. Ufa olimba-gawo sintering akhoza kugawidwa mu mitundu iwiri: unit-system olimba-gawo sintering ndi Mipikisano dongosolo olimba-gawo sintering malinga ndi chiwerengero cha zigawo zikuluzikulu.

Pamwambapa ndi chiyambi cha wamba sintering njira ufa metallurgy.Sintering mu ufa zitsulo ndi mkulu-kutentha mankhwala ndondomeko zinanso Chili chogwirana kapena lotayirira matupi ufa kusintha mphamvu ndi katundu.

Chiyambireni kukhazikitsidwa kwake, Minxin Powder Metallurgy yakhala ikudzipereka pa kafukufuku ndi chitukuko, kupanga ndi kugulitsa zitsulo zachitsulo ndi zitsulo.ufa jekeseni akamaumba. Kwa zaka khumi, gulu la R&D lakhala likuyang'ana kwambiri pakupanga zitsulo zolondola kwambiri za ufa: magawo olondola omwe amapangidwa ndi mafuta, zida zamapangidwe, magiya, zitsulo zosapanga dzimbiri zitsulo ndi zinthu zosiyanasiyana zopangira jekeseni. zakuthupi: mndandanda mkuwa, mndandanda chitsulo mkuwa, mndandanda chitsulo, aloyi zitsulo, zosapanga dzimbiri ceramics, etc..
