welding electrode 2% cerium WC20 cerium tungsten electrode
A na-ejikọta Tungsten na 2% ceria iji mepụta tungsten-cerium oxide composite nke a na-ejikarị eme ihe dị ka ihe na-adịghị eme redio maka tungsten electrodes dị egwu na ngwa ịgbado ọkụ.
Agba nke tungsten nwere 2% ceria nwere ike ịdị iche mana ọ na-abụkarị isi awọ ma ọ bụ na-acha ọcha. Ndo a kapịrị ọnụ nwere ike ịdabere na ihe ndị dị ka usoro mmepụta ihe na mkpuchi ma ọ bụ ọgwụgwọ ọ bụla a na-etinye na ihe.
Tungsten Thoriated na cerium tungsten bụ ma tungsten electrodes maka ịgbado ọkụ, ma ha nwere dị iche iche mejupụtara na Njirimara:
1. Tungsten na-atụ egwu:
-Electrodes tungsten na-atụ ụjọ nwere obere thorium oxide (na-abụkarị 1-2%). Mgbakwunye nke thorium na-eme ka njirimara ikuku electron nke electrode dịkwuo mma, na-eme ka ọ dịkwuo mfe ịmalite na ịnọgide na-agbado arc.
-Thoriated tungsten mara maka ikike ibu ya dị elu ugbu a, ezigbo nkwụsi ike na ogologo ndụ. A na-ejikarị ya na ngwa ịgbado ọkụ DC, karịsịa maka ihe ịgbado ọkụ dị ka carbon steel, igwe anaghị agba nchara, nickel alloys na titanium.
2. Tungsten cerium:
Cerium tungsten electrodes nwere cerium oxide dị ka ihe alloying. Ngwakọta cerium tungsten nkịtị nwere 1.5-2% cerium oxide.
- Cerium tungsten nwere ezigbo mmalite na nkwụsi ike, ọkachasị na ngwa ịgbado ọkụ dị ala. Ọ dabara maka ịgbado ọkụ AC na DC ya mere dabara adaba maka ihe dị iche iche na usoro ịgbado ọkụ.
- A na-ahọrọkarị cerium tungsten ka ọ bụrụ ihe ọzọ na-adịghị eme redio na thorium tungsten iji gboo nchegbu banyere ihe egwu ahụike nwere ike jikọta na mkpughe thorium.
Na nchịkọta, ebe a na-eji ma tungsten electrodes na cerium tungsten electrodes na-agbado ọkụ, ha nwere nhazi dị iche iche ma dabara maka ngwa ịgbado ọkụ dị iche iche na ọnọdụ. A maara Thoriated tungsten maka ikike ibu ya dị elu ugbu a ma na-ejikarị ya na ịgbado ọkụ DC, ebe cerium tungsten nwere ezigbo mmalite na nkwụsi ike ma dabara adaba maka ịgbado ọkụ AC na DC.
Ee, 2% nke tungsten eletrọd na-atụ egwu ka a na-ewere na ọ dị ntakịrị redioaktivu n'ihi ọnụnọ nke thorium oxide na ngwakọta electrode. Thorium bụ ihe na-eme na redioaktivu a na-ahụ n'ime elektrọd tungsten nke na-ewepụta mkpụrụ irighiri alfa dị ala. Ọ bụ ezie na ọkwa ọrụ redio dị obere, ọ ka dị mkpa ijikwa ma tụfuo elektrọd tungsten dị egwu iji belata ikpughe nwere ike.
N'ihi ọdịdị redioaktivu nke thorium, iji, njikwa na mkpofu nke thorium tungsten electrodes chọrọ nchekwa na nhazi usoro. N'ihi ya, a na-enwe mgbanwe n'ebe ndị ọzọ na-abụghị redioactive dị ka tungsten cerium, tungsten lanthanate ma ọ bụ ndị ọzọ obere ụwa ọcha doped tungsten electrodes, karịsịa na ụlọ ọrụ ebe nchekwa ndị ọrụ na gburugburu ebe obibi dị oké mkpa.
