No ke aha i loaʻa ai i kā mākou pā lole ke kūpaʻa maikaʻi o ka lole?

1. ʻO ke ʻano kemika i uhi ʻia ke kī.

ʻO nā mea nui o nā papa Wodon ʻo C(%) :3.0-5.0 a me Cr(%):25-40.

ʻO kēia ʻāpana kemika ka hopena i ka nui o nā ʻāpana paʻakikī Cr7C3 chrome carbide. ʻO ka micro-hardness (a hiki i HV1800)o kēia mau meaʻO nā ʻāpana ma loko o ka papa e hōʻoiaʻiʻo i kahi ʻili kūpaʻa loa.

 

 

 

 

 

 

 

 

 

 

Hoʻāʻo Hana:

Nā lako hoʻāʻo: Huila laholio one Quartzmīkini hoʻāʻo ʻūlū ʻana.

Nā Kūlana: 1. Ke koho ʻana i nā hāpana like like no nā mea like ʻole a me nā mea hana papa komo, a kau iā lākouma lalo o nā kūlana hana like i loko o kā mākou lako hoʻāʻo.

2.45 mau minuke no kēlā me kēia hāpana

 

                           45 mau minuke no kēlā me kēia hāpana

 

 

 

 

 

 

 

 

 

 

 

2. ʻO ke ʻano liʻiliʻi o ka chromium carbide

ʻO ke kūpaʻa o ka pā lole e pili nui ana i ka paʻakikī, ke ʻano, ka nui, ka nui a me ka hoʻolaha ʻana o ka chromiumnā ʻāpana paʻakikī carbide.

 

E like me kāu e nānā ai ma ke kiʻi, ʻoi aku ka nui o ka carbide (Cr7C3) ma ka microstructure ma mua o 50%.

 

3. Ka ikaika hoʻopaʻa ma waena o ka uhi a me ka papa kumu.

Hoʻopili maikaʻi loa ka uhi a me ka papa kumu. E komo ka uhi i loko o ka papa kumu ma kahi o 0.8mm-1.8mm, e hōʻea anaa i 350Mpa i kā mākou mau hoʻokolohua.
