Mfaso bɛn na ɛwɔ bimetal wear-ɛko tia nsateaa so?

Mfaso a ɛwɔ bimetal wear so{0}}ɛko tia elbow / bimetal wear-a ɛko tia composite elbow:
1. Good Wear Resistance Medium Medium Rare Earth Wear-Wɔn ho yɛ den, wobetumi adi den no so sɛnea adwumayɛ tebea ahorow te, wobetumi adi chromium denyɛ no so wɔ HRC45-65 mu, na ɛwɔ toughness a ɛkorɔn.
2. Bimetal wear-a ɛko tia elbow no wɔ corrosion resistance a ɛyɛ den, ɔhyew a ɛkɔ soro a ɛko tia ne nea ɛko tia a ɛkorɔn. Esiane sɛ R carbides no te ne ne su, na matrix a ɛwɔ solid solution content cr no wɔ ɔhyew a ɛko tia ne corrosion resistance a emu yɛ den, na afei MO a wɔde ka ho no ma ɛda corrosion resistance a ɛkyɛn so adi na ɛyɛ nea ɛko tia wɔ ɔhyew a ɛkɔ soro anaasɛ corrosive mmeae a ɛho yɛ na no, na wɔde asase dodow bi ka ho ma ɛma alloy no mu nhyehyɛe no yɛ compact kɛse, na wɔyɛ film a ɛbɔ ho ban fi surface no ho ma esiw carbon no ano. a ɛkɔ soro a ɛko tia ɔbrɛ ne corrosion a ɛko tia; Adefo wɔ boron dodow bi mu ma ɛyɛ den a alloy nsakrae kɔ denyɛ a wontumi nnya denam carburization, na rich wɔ dodow bi Mn ma nkɔanim ɔbrɛ a ɛko tia alloy no, ma alloy no wear resistance yɛ papa sen high chromium alloys ne rare earth alloys.
3. Weldability a ɛwɔ bimetallic wear-a ɛko tia composite elbow no ye. In the past, high-chromium alloys and rare-earth alloys have extremely high carbon content in order to achieve a certain hardness, so the weldability is extremely poor, while medium-chromium rare-earth boron alloys basically It is improved by boron, so the weldability is better than that of high chromium alloy and rare earth alloy, but it is not ideal. Ɛsɛ sɛ yɛde yɛn ho to weldability a A3 ne 16mn wɔ akyi ɔfasu no so na ama yɛanya welding ahoɔden a ɛfata, sɛnea ɛbɛyɛ a elbow no nyinaa yɛ ahobammɔ ne ahotoso. .
