Ukuxinana kweTungsten Carbide

I-Tungsten Carbide, eyaziwa njengamazinyo emizi-mveliso, yimveliso eqhelekileyo esezantsi. Idume ngeempawu zayo ezigqwesileyo ezibandakanya ubunzima obuphezulu, amandla aphezulu, ukuxinana okuphezulu, ukumelana nokunxiba, kunye nokumelana nomhlwa, ukuze, inokwenziwa ibe ngamasuntswana okomba ahlukeneyo, abasiki, izixhobo zokomba amatye, izixhobo zemigodi, izixhobo zokunxiba, ii-cylinder liners. , kwaye nangokunjalo. Kwishishini, siya kusebenzisa iiparamitha ezininzi zokuvavanya nokuqinisekisa ukuba iimveliso ze-tungsten carbide zikumgangatho ophezulu. Kule nqaku, isiseko somzimba esisisiseko, ukuxinana, kuya kuthethwa ngaso.

Yintoni ingxinano?

Uxinaniso luphawu olubalulekileyo lwepropathi yomatshini ukubonisa ubunzima bekhabhide enesamente ngomthamo weyunithi. Umthamo esiwukhankanyileyo apha, uquka umthamo weepores kwizinto eziphathekayo. Ngokwenkqubo yamazwe ngamazwe yeeyunithi kunye neeyunithi zokulinganisa ngokusemthethweni zaseTshayina, ubuninzi bumelwe ngumqondiso ρ, kwaye iyunithi yoxinaniso yi-kg/m3.

Ubuninzi be-tungsten carbide

Ngaphantsi kwenkqubo efanayo yokuvelisa kunye neeparitha ezifanayo, ubuninzi be-carbide ene-cemented buya kutshintsha kunye nokutshintsha kokwakhiwa kweekhemikhali okanye ukulungiswa komlinganiselo wezinto eziluhlaza.

Amacandelo aphambili e-YG series carbides cemented carbides yi-tungsten carbide powder kunye ne-cobalt powder. Ngaphantsi kweemeko ezithile, njengoko umxholo we-cobalt ukhula, ubuninzi be-alloy buyancipha, kodwa xa ixabiso elibalulekileyo lifikeleleke, uluhlu lokuguquguquka kobuninzi luncinci. Ubuninzi be-alloy ye-YG6 yi-14.5-14.9g/cm3, ubuninzi be-YG15 alloy yi-13.9-14.2g/cm3, kunye nobuninzi be-YG20 ingxube ye-13.4-13.7g/cm3.

Amacandelo aphambili ochungechunge lwe-YT ye-cemented carbide yi-tungsten carbide powder, i-titanium carbide powder, kunye ne-cobalt powder. Ngaphantsi kweemeko ezithile, njengoko umxholo we-titanium carbide powder ukhula, ubuninzi be-alloy buyancipha. YT5 ingxinano yengxubevange 12.5-13.2g/cm3, YT14 ingxubevange yengxubevange 11.2-12.0g/cm3, YT15 ingxubevange yengxubevange 11.0-11.7g/cm3

Amacandelo aphambili e-YW series cemented carbide yi-tungsten carbide powder, i-titanium carbide powder, i-tantalum carbide powder, i-niobium carbide powder, kunye ne-cobalt powder. Ubuninzi be-alloy ye-YW1 yi-12.6-13.5g/cm3, ubuninzi be-YW2 ingxubevange yi-12.4-13.5g/cm3, kunye nobuninzi be-YW3 alloy yi-12.4-13.3g/cm3.

Ngenxa yobuninzi bayo, i-carbide ene-cemented ingenziwa kwiimveliso ezahlukeneyo, ezifana ne-counterweights mechanical, i-weighting rods ezisetyenziswa kumashishini okugaya afana ne-oyile, i-clock pendulum, ii-ballasts zokuhamba ngeeseyile, ukuhamba ngeenqanawa, njl njl. ,  enokuqinisekisa ibhalansi yezinto ezikwimeko esebenzayo okanye engatshintshiyo, okanye isindise kakhulu umsebenzi wabasebenzi.

Izinto ze-tungsten carbide density

Ubuninzi bunxulumene nokwakhiwa kwezinto, umlinganiselo wezinto ezikrwada, i-microstructure, inkqubo yemveliso, iiparamitha zenkqubo, kunye nezinye izinto. Ngokuqhelekileyo, iindawo zokusetyenziswa kwee-carbides ezine-cemented kunye noxinaniso olwahlukeneyo nazo zahlukile. Oku kulandelayo kwazisa ikakhulu imiba enempembelelo yoxinaniso lwealloyi.

1. Ukwakhiwa kwezinto

I-carbide enesamente inokuqulunqwa ngamacandelo amabini, i-tungsten carbide powder (i-WC powder) kunye ne-cobalt powder (i-Co powder), okanye i-powder ezintathu: i-WC powder, i-TiC powder (i-titanium carbide powder) kunye ne-Co powder, okanye i-WC powder. Ipowder, i-TiC powder, i-TaC powder (i-tantalum carbide powder), i-NbC powder (i-niobium carbide powder), kunye ne-Co powder. Ngenxa yokwakheka okuhlukeneyo kwezixhobo ze-alloy, ubuninzi be-alloy iyahluka, kodwa izigaba ziyafana: ubuninzi be-YG6 ye-alloy yi-14.5-14.9g / cm³, ubuninzi be-YT5 alloy yi-12.5-13.2g / cm³, kwaye ubuninzi be-alloy ye-YW1 yi-12.6-13.5g/cm³.

Ngokuqhelekileyo, ubuninzi be-tungsten-cobalt (YG) i-carbide ye-cemented yanda ngokunyuka komxholo we-WC powder. Ngokomzekelo, ubuninzi be-alloy kunye ne-WC ye-powder content ye-94% (YG6 alloy) yi-14.5-14.9g / cm³, kunye ne-WC ye-powder content Ubuninzi be-85% ye-alloy (YG15 alloy)yi 13.9-14.2g/cm³.

Ubuninzi be-tungsten-titanium-cobalt (YT) i-alloys enzima iyancipha ngokunyuka komxholo we-TiC powder. Ngokomzekelo, ubuninzi bee-alloys kunye ne-TiC ye-powder content ye-5% (YT5 alloy) yi-12.5-13.2g / cm³, kunye ne-TiC powder content yi-15%. Ubuninzi be-alloy (YT15 alloy) yi-11.0-11.7g/cm³.

2. IMicrostructure

I-Porosity ibangelwa ikakhulu ngama-pores kunye nokuncipha kwaye isalathisi esibalulekileyo sokugweba umgangatho we-carbide ene-cemented. Izizathu eziphambili zokubunjwa kwe-carbide pores zibandakanya ukutshisa ngokugqithiseleyo, ukufakwa kwezinto eziphilayo, ukufakwa kwesinyithi, iipropati ezixinzelelekileyo, kunye nee-agent zokubumba ezingalingani.

Ngenxa yobukho be-pores, ubuninzi bokwenene be-alloy bungaphantsi koxinzelelo lwethiyori. I-pores enkulu okanye ngaphezulu, i-alloy encinci encinci iphantsi kobunzima obunikiweyo.

3. Inkqubo yokuvelisa

Inkqubo yokuvelisa ibandakanya inkqubo yesinyithi somgubo kunye neteknoloji yokubumba i-injection. Iziphene ezifana ne-carburizing, ukutshisa ngaphantsi, ukuhlambalaza, ukuxubha, ukukrazula, kunye nokungazinzi ngexesha lokucinezela kunye ne-sintering kuya kukhokelela ekunciphiseni koxinano lwe-carbide enesamente.

4. Indawo yokusebenza

Ngokuqhelekileyo, ngokutshintsha kweqondo lokushisa okanye uxinzelelo, umthamo okanye ubuninzi be-alloy buya kutshintsha ngokuhambelanayo, kodwa utshintsho luncinci kwaye lunokungahoywa.

Ukuba unomdla kwiimveliso ze-tungsten carbide kwaye ufuna ulwazi oluninzi kunye neenkcukacha, ungaqhagamshelana nathi.
