Ingxube yethusi ye-tungstenayigcini nje ngokuba nesici sokunwebeka esiphansi se-tungsten, kodwa futhi inesici esiphezulu se-thermal conductivity yethusi.Ngokushintsha ingxenye ye-tungsten nethusi, i-coefficient yokwandisa ukushisa kanye nomsebenzi we-thermal conductivity we-tungsten ne-alloy yethusi iyashintshwa, ngakho insimu yesicelo se-tungsten ne-alloy yethusi ibanzi kakhulu.Ingxubevange yethusi ye-Tungsten isetshenziswa kakhulu ezintweni ezisetshenziswayo ze-semiconductor ngenxa yezakhiwo zayo ezinhle zomzimba nezomshini, ikhono elihle lokuqhuba lamanje, kanye ne-coefficient efanayo yokwandisa okushisayo ngamawafa e-silicon nezinto zobumba.
Okuhlukile kwe-tungsten copper electroplating ukuthi kuyanconywa ukwenza ukuhlolwa kokuguga ngokobuchwepheshe obukhona be-electroplating namasampula e-electroplating ngaphambi kwe-electroplating.Ingxubevange ye-tungsten-copper ene-electroplated ifakwa esithandweni sevacuum ku-800℃ futhi iphathwe ngokulondolozwa kokushisa cishe imizuzu engama-20.
Uma kungekho ukusabela okubi okufana namabhamuza nokushintsha kombala okutholakala ku-alloy yethusi ye-tungsten ngemva kwehhavini, kubonisa ukuthi ayikho inkinga ngobuchwepheshe be-electroplating, futhi i-electroplating ye-tungsten-copper ingenziwa ngokwalobu buchwepheshe.Esimeni sokusabela okungekuhle okufana namabhamuza nokushintsha kombala kwe-tungsten-copper alloy, sicela uyeke ukusebenzisa lobu buchwepheshe ukuze ugweme ukumoshakala kwezisetshenziswa.Sicela uthintane nabasebenzi be-electroplating abaqeqeshiwe ukuze nixoxe ngohlelo lokuthuthukisa.Ngenxa yokuthi i-tungsten yethusi ingxubevange yenziwa inhlanganisela ye-tungsten nethusi, futhi i-tungsten yensimbi ayincibiliki nezinye izinsimbi, ngakho-ke kunzima ukwenza ubuchwepheshe be-electroplating.
Mayelana nendlela ye-electroplating ye-tungsten-copper alloy: I-alloy ye-tungsten yethusi kufanele ihlanzwe ngaphambi kwe-electroplating, kusetshenziswa uketshezi lokuhlanza lwe-ultrasonic kanye nokungathathi hlangothi, ukungcola okusendaweni ye-tungsten-yethusi kuzohlanzwa, ukuze kwandiswe amandla okunamathela kwendawo ye-tungsten-yethusi.Kodwa kufanele kuqashelwe ukuthi i-ejenti yokuhlanza ivinjelwe ukusebenzisa i-asidi eqinile kanye nezinto ze-alkali.Ngaphezu kwalokho, ngaphambi kokuhlanza kanye nobuchwepheshe be-electroplating, isikhawu phakathi kokubili akufanele sibe side kakhulu.Ngemuva kokuhlanza, i-electroplating kufanele yenziwe ngokushesha.
