Kedu ihe kpatara efere anyị ji enwe nguzogide dị mma nke ukwuu?

1. Ihe mejupụtara kemịkal machie bụ isi.

Isi ihe mejupụtara efere Wodon bụ C (%): 3.0-5.0 na Cr (%): 25-40.

Ogo nke kemịkal a na -ebute irighiri ihe siri ike nke Cr7C3 chrome carbide. Micro-ekweghị ekwe (ruo HV1800) nke ndị a irighiri ihe dị na oyi akwa niile ga -ekwe nkwa elu na -eguzogide ọgwụ.

2. Chromium carbide microstructure

Iguzogide iyi nke efere eyi na -adaberekarị n'ịdị ike, ọdịdị, nha, ego na nkesa chromium carbide ike ahụ.

 

Dịka ị nwere ike lelee na foto a, pere mpe pere mpe nke carbide (Cr7C3) na microstructure dị karịa 50%.

 

3. Ike njikọ n'etiti ihe machie na efere isi.

Mkpuchi na efere ala na -ejikọ nke ọma. Mkpuchi ahụ ga-abanye n'ime efere ihe dị ka 0.8mm-1.8mm, na-eru ruo 350Mpa na ule anyị.
