(1) Ko nga ahuatanga o te raima konumohe konumohe hiato konumohe kei roto ko te matūriki (tae atu ki te pahau) te whakakaha me te whakakaha muka.Ko nga rauemi e whakamahia ana mo te whakakaha ko te B, CB, SiC, etc.
I te wa e whakawerahia ana, ka werahia te matrix matrix, ka ngawari te mahi a te matrix Al me te wahanga whakakaha, penei i te tere o te horahanga o Si i roto i te whakarewa whakakii ki te whakarewa turanga me te hanga o te paparanga putunga pakaru.Na te nui o te rereketanga o te whakarea roha raina i waenga i te Al me te wahanga whakakaha, ko te whakamahana whakawera kore tika ka puta te ahotea waiariki i te atanga, he ngawari ki te pakaru tahi.Hei taapiri, he ngoikore te makuku i waenga i te whakarewa whakakii me te waahanga whakakaha, na reira me rongoa te mata o te whakahiato, me whakamahi ranei te whakarewa whakakii, me te whakamahi i te raima korehau kia taea.
(2) Ka taea te parai i nga mea whakahiato me te tukanga B, SiC matūriki konumohe matrix matrix composites whakakaha, me te maimoatanga mata i mua i te whakapiri ka taea te mahi ma te huri kirikiri, te horoi paraihe waea, te horoi alkali, te whakakikorua nickel electroless ranei (0.05mm te matotoru o te paninga).Ko te whakarewa whakakii ko s-cd95ag, s-zn95al me s-cd83zn, ka whakamahanahia e te mura oxyacetylene ngawari.I tua atu, ka taea te whiwhi kaha hononga teitei ma te tarai i te brazing me te s-zn95al solder.
Ka taea te whakamahi i te raima korehau mo te hononga o nga whakahiato matrix matrix 6061.I mua i te parai, me whakamarokehia te mata ki te 800 pepa abrasive i muri i te hurihanga, katahi ka tahuna ki roto i te oumu i muri i te horoinga ultrasonic i roto i te acetone.Al Si brazing whakakī whakarewa te nuinga whakamahia.Hei aukati i te whakamaaramatanga o Si ki roto i te konganuku turanga, ka taea te whakakikorua i tetahi paparanga arai parakore konumohe konumohe ki runga i te mata parai o te rauemi hiato, te b-al64simgbi (11.65i-15mg-0.5bi) ranei te whakakikorua i te whakarewa me te whakarewa. ka taea te kowhiri i te kaha brazing iti.Ko te awhe o te rewa o te whakarewa whakakikorua he 554 ~ 572 ℃, ka taea te 580 ~ 590 ℃ te wera o te wera, ko te wa whakamahana he 5min, me te kaha o te kutikuti o te hononga he nui atu i te 80mpa
Mo te matūriki kauwhata whakakaha konumohe matrix hiato, ko te whakamarumaru i roto i te oumu hau whakamarumaru te huarahi tino angitu i naianei.Hei whakapai ake i te makuku, me whakamahi te Al Si solder kei roto Mg.
Pērā i te konumohe korehau parai, ka taea te whakapai ake i te makuku o nga hiato konumohe matrix ma te whakauru i te kohu mg, Ti momi ranei me te taapiri i te nui o Mg.
