ʻElekode Kuʻi Paʻakikī a me ke Kūpaʻa ʻo ECoCr-B (Cobalt 12) Cobalt
ʻAno Alloy: A5.13, SOLID SURFACING Nā Electrodes a me nā Rods Welding, A5.13
Hiki ke manaʻo ʻia ʻo ECoCr-B Cobalt Alloy 12 he mea hoʻohuihui waena ma waena o Cobalt Alloy 6 a me Cobalt Alloy 1. Loaʻa iā ia kahi hapa nui o nā carbides paʻakikī a palupalu ma mua o Cobalt Alloy 6, a ua hoʻonui ʻia ke kūpaʻa ʻana i ka ʻino haʻahaʻa, ka abrasion, a me ka paheʻe koʻikoʻi me ka mālama ʻana i ka hopena kūpono a me ke kūpaʻa cavitation. Hoʻohana pinepine ʻia ʻo Cobalt Alloy 12 i hoʻopili ponoʻī ʻia a i ʻole e holo kūʻē i ka Cobalt Alloy 6 a i ʻole 1. ʻO ka ʻike tungsten kiʻekiʻe e hāʻawi i nā waiwai wela kiʻekiʻe maikaʻi aʻe i hoʻohālikelike ʻia me Cobalt Alloy 6, a hiki ke hoʻohana ʻia i nā mahana a hiki i kahi o 700⁰C. Hoʻohana pinepine ʻia ʻo Cobalt Alloy 12 no nā mea ʻokiʻoki e pono ai ke kū i ka abrasion, ka wela a me ka corrosion.
Nā Hoʻohana Maʻamau: nā kaola ʻoki kaulahao; nā niho ʻoki; nā make extrusion
