No ke aha i loaʻa ai i kā mākou papa lole ke kūpaʻa maikaʻi?

1. ʻO ka hoʻohui kemika overlay ke kī.

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

ʻO kēia ʻāpana kemika ka hopena i ka nui o nā mea paʻakikī Cr7C3 chrome carbide. ʻO ka micro-hardness (a hiki i HV1800)o keia mau meae hōʻoiaʻiʻo ʻia nā ʻāpana a puni ka papa i kahi ʻili kūpaʻa maikaʻi loa.

 

 

 

 

 

 

 

 

 

 

Hōʻike hoʻokō:

Mea ho'āʻo: quartz one rubber huilamīkini hoʻāʻo abrasion.

Nā Kūlana: 1. Ke koho ʻana i nā ʻāpana like ʻole no nā mea like ʻole a ʻaʻahu i nā mea hana pā, a kau iā lākou.ma lalo o nā kūlana hana like i kā mākou mea hoʻāʻo.

2.45 mau minuke no kēlā me kēia hōʻike

 

                           45 mau minuke no kēlā me kēia hōʻike

 

 

 

 

 

 

 

 

 

 

 

2. Chromium carbide microstructure

ʻO ka pale ʻana o ka pā lole e hilinaʻi nui ʻia i ka paʻakikī, ke ʻano, ka nui, ka nui a me ka hāʻawi ʻana o ka chromiumcarbide hard particles.

 

Hiki iā ʻoe ke nānā i ke kiʻi, ʻoi aku ka hapa nui o ka carbide (Cr7C3) ma ka microstructure ma luna o 50%.

 

3. ʻO ka ikaika hoʻopaʻa ma waena o ka uhi a me ka pā kumu.

Hoʻopili maikaʻi loa ka uhi ʻana a me ka papa kumu. E komo ka overlay i loko o ka pā kumu ma kahi o 0.8mm-1.8mm, hikia hiki i 350Mpa i kā mākou mau hoʻokolohua.
