Boima ba Tungsten Carbide

Tungsten Carbide, e tsejoang ka hore ke meno a indasteri, ke sehlahisoa se tloaelehileng se tlase. E tumme ka thepa ea eona e ntle e kenyelletsang boima bo phahameng, matla a phahameng, letsoalo le phahameng, ho hanyetsa ho roala, le ho hanyetsa kutu, e le hore e ka etsoa ka likotoana tse fapaneng tsa ho cheka, li-cutters, lisebelisoa tsa ho cheka mafika, lisebelisoa tsa merafo, likarolo tsa ho roala, li-cylinder liner. , joalo joalo. Ka indasteri, re tla sebelisa li-parameter tse ngata ho hlahloba le ho netefatsa hore lihlahisoa tsa tungsten carbide ke tsa boleng bo phahameng. Sehloohong sena, ho tla buuoa ka tšobotsi ea motheo ea 'mele, boima ba' mele.

Density ke eng?

Density ke index ea bohlokoa ea thepa ea mochini ho bonts'a boima ba carbide e entsoeng ka samente ka bophahamo ba yuniti. Molumo oo re o boletseng mona, o kenyelletsa molumo oa li-pores ka thepa. Ho ea ka tsamaiso ea machaba ea likarolo le litekanyetso tsa molao tsa Chaena, boima bo emeloa ke letšoao ρ, 'me tekanyo ea boima ke kg/m3.

Boima ba tungsten carbide

Tlas'a ts'ebetso e ts'oanang ea tlhahiso le li-parameter tse tšoanang, boima ba carbide e entsoeng ka samente bo tla fetoha ka phetoho ea metsoako ea lik'hemik'hale kapa phetoho ea tekanyo ea thepa e tala.

Likarolo tsa mantlha tsa letoto la YG le li-carbide tse samenteng ke phofo ea tungsten carbide le phofo ea cobalt. Tlas'a maemo a itseng, ha litaba tsa cobalt li ntse li eketseha, letsoalo la alloy le fokotseha, empa ha boleng ba bohlokoa bo fihleloa, tekanyo ea ho fetoha ha sekhahla e nyenyane. The density ea YG6 alloy ke 14.5-14.9g/cm3, density ea YG15 alloy ke 13.9-14.2g/cm3, le density ea YG20 alloy ke 13.4-13.7g/cm3.

Likarolo tsa mantlha tsa letoto la YT le entsoeng ka samente ea carbide ke phofo ea tungsten carbide, titanium carbide powder, le phofo ea cobalt. Tlas'a maemo a itseng, ha litaba tsa titanium carbide phofo li ntse li eketseha, sekhahla sa alloy se fokotseha. YT5 alloy density 12.5-13.2g/cm3, YT14 alloy density 11.2-12.0g/cm3, YT15 alloy density 11.0-11.7g/cm3

Likarolo tse ka sehloohong tsa letoto la YW le entsoeng ka samente carbide ke tungsten carbide phofo, titanium carbide phofo, tantalum carbide phofo, niobium carbide phofo, le cobalt phofo. The density of YW1 alloy ke 12.6-13.5g/cm3, density ea YW2 alloy ke 12.4-13.5g/cm3, le density ea YW3 alloy ke 12.4-13.3g/cm3.

Ka lebaka la boima ba eona bo phahameng, carbide e entsoeng ka samente e ka etsoa lihlahisoa tse fapa-fapaneng, tse kang li-counterweights, li-weighting rods tse sebelisoang liindastering tsa ho cheka tse kang oli, li-clock pendulum, li-ballasts bakeng sa ho tsamaea ka sekepe, ho tsamaea ka sekepe, joalo-joalo. ,  e leng se ka netefatsang ho leka-lekana ha lintho boemong ba ho sebetsa kapa bo sa sisinyeheng, kapa ho pholosa mosebetsi oa basebetsi haholo.

Lintlha tse mabapi le tungsten carbide density

Density e amana le sebopeho sa thepa, karo-karolelano ea thepa e tala, microstructure, ts'ebetso ea tlhahiso, mekhahlelo ea ts'ebetso le lintlha tse ling. Ka kakaretso, masimo a ts'ebeliso ea li-carbide tse samente tse nang le li-density tse fapaneng le tsona li fapane. Lintlha tse latelang li kenyelletsa haholo lintlha tse susumetsang tsa alloy density.

1. Ho hlophisoa ha lintho

Carbide e entsoeng ka samente e ka etsoa ka li-powders tse peli, tungsten carbide powder (WC powder) le cobalt powder (Co powder), kapa li-powders tse tharo: phofo ea WC, phofo ea TiC (titanium carbide powder) le Co powder, kapa esita le phofo ea WC. Phofo, phofo ea TiC, phofo ea TaC (tantalum carbide powder), NbC phofo (niobium carbide powder), le Co powder. Ka lebaka la mefuta e fapaneng ea lisebelisoa tsa alloy, boima ba motsoako bo fapane, empa mekhahlelo e tšoana: boholo ba motsoako oa YG6 ke 14.5-14.9g/cm³, boima ba motsoako oa YT5 ke 12.5-13.2g / cm³, mme boima ba motsoako oa YW1 ke 12.6-13.5g/cm³.

Ka kakaretso, boima ba tungsten-cobalt (YG) carbide e entsoeng ka samente bo eketseha ka ho eketseha ha WC phofo. Ka mohlala, boima ba alloy e nang le phofo ea WC ea 94% (YG6 alloy) ke 14.5-14.9g / cm³, le WC powder content The density of 85% alloy (YG15 alloy)ke 13.9-14.2g/cm³.

Boima ba li-alloys tse thata tsa tungsten-titanium-cobalt (YT) bo fokotseha ka ho eketseha ha lihlahisoa tsa phofo ea TiC. Mohlala, boima ba li-alloys tse nang le phofo ea TiC ea 5% (YT5 alloy) ke 12.5-13.2g/cm³, 'me karolo ea phofo ea TiC ke 15%. Boima ba motsoako (YT15 alloy) ke 11.0-11.7g/cm³.

2. Microstructure

Porosity e bakoa haholo ke li-pores le shrinkage mme ke sesupo sa bohlokoa sa ho ahlola boleng ba carbide e entsoeng ka samente. Mabaka a ka sehloohong a ho thehoa ha li-pores tsa carbide tse entsoeng ka samente li kenyelletsa ho chesa ho feta tekano, li-organic inclusions, li-inclusions tsa tšepe, thepa e fokolang ea ho hatella, le li-agent tse sa tšoaneng tsa ho bōpa.

Ka lebaka la boteng ba li-pores, boima ba 'nete ba alloy bo tlase ho feta tekano ea theory. Li-pores tse kholoanyane kapa tse ngata, motsoako o fokolang haholo o boima bo fanoeng.

3. Mokhoa oa tlhahiso

Ts'ebetso ea tlhahiso e kenyelletsa ts'ebetso ea metallurgy ea phofo le theknoloji ea ho bopa ente. Litšitiso tse joalo ka carburizing, ho chesoa ka tlase, ho silafatsa, ho phunya, ho ebola le ho se kobehe nakong ea ho hatelloa le ho siling ho tla lebisa ho fokotseheng ha letsoalo la carbide e entsoeng ka samente.

4. Tikoloho ea mosebetsi

Ka kakaretso, ka phetoho ea mocheso kapa khatello, molumo kapa boima ba alloy le tsona li tla fetoha ka tsela e tšoanang, empa phetoho e nyenyane 'me e ka hlokomolohuoa.

Haeba u thahasella lihlahisoa tsa tungsten carbide 'me u batla boitsebiso bo eketsehileng le lintlha, u ka ikopanya le rona.
