He aha te take he pai rawa te ātete o tā mātou pereti kakahu ki te kakahu?

1. Ko te hanganga matū paparua te mea nui.

Ko ngā kai matua o ngā pereti Wodon ko C(%) :3.0-5.0 me Cr(%):25-40.

Nā tēnei ōwehenga matū ka hua ake he nui ngā matūriki mārō Cr7C3 chrome carbide. Ko te mārō iti (tae atu ki te HV1800)o ēneiMā ngā matūriki puta noa i te paparanga ka tino ātete te mata ki te kakahu.

 

 

 

 

 

 

 

 

 

 

Whakamātautau Mahi:

Taputapu whakamātautau: Wira rapa onepu kuatamīhini whakamātautau pakū.

Ngā Tikanga: 1. Te whiriwhiri i ngā tauira ine-rite mō ngā rauemi rerekē me ngā kaihanga pereti kakahu, ka whakanoho ki rotoi raro i ngā tikanga mahi mau ōrite i roto i ā mātou taputapu whakamātautau.

2.45 meneti mō ia tauira

 

                           45 meneti mō ia tauira

 

 

 

 

 

 

 

 

 

 

 

2. Hanganga iti o te chromium carbide

Ko te ātete kakahu o te pereti kakahu e whakawhirinaki ana ki te pakeke, te āhua, te rahi, te nui me te tohatoha o te chromium.ngā matūriki mārō kāpira.

 

Ka taea e koe te tirotiro i te pikitia, kei runga ake i te 50% te wāhanga rōrahi kāpira (Cr7C3) i runga i te hanganga moroiti.

 

3. Te kaha o te here i waenga i te paparanga me te pereti turanga.

He tino pai te piri o te paparanga me te pereti turanga. Ka uru te paparanga ki roto i te pereti turanga tata ki te 0.8mm-1.8mm, ka tae atu kitae atu ki te 350Mpa i roto i ā mātou whakamātautau.
