Usoro ịgbado ọkụ nke PDC

Dị ka akụkọ ikpeazụ anyị na-egosi, dị ka usoro kpo oku si dị, usoro brazing nwere ike kewaa n'ime ọkụ brazing, vacuum brazing, vacuum diffusion bonding, high-frequency induction brazing, laser beam welding, wdg N'isiokwu a, ka anyị gaa n'ihu n'elu ma bịa. na brazing induction ugboro ugboro, yana ịgbado ọkụ laser.

Induction brazing dị elu nke PDC

Induction brazing dị elu na-eji ntinye elektrọn iji gbanwee ike elektrọn ka ọ bụrụ ike ọkụ na igwe brazing filler na workpiece, na-ekpo ọkụ metal brazing ka ọ bụrụ ọnọdụ gbazere. PDC's high-frequency induction brazing usoro bụ isi teknụzụ maka brazing PDC ịcha ngwaọrụ.

Uru nke PDC induction brazing dị elu:

1.   Igwe kpo oku na-agba ọsọ ngwa ngwa, nke nwere ike belata mfu ọkụ nke oyi akwa PDC polycrystalline diamond yana ogo oxidation nke carbide cemented.

2.   hụ na akụkụ ahụ ziri ezi nke akụkụ ahụ

3.   fọrọ nke nta ka ọ bụrụ mmetọ gburugburu ebe obibi

4.   dị mfe ịghọta akpaaka mmepụta.

PDC laser beam ịgbado ọkụ

Laser Beam Welding na-eji nnukwu ike njupụta laser ọkụ dị ka isi iyi ọkụ, site n'ịchịkwa laser obosara obosara, ike, ike kacha elu, ugboro ugboro, na paramita ndị ọzọ iji mee ka workpiece ruru omimi nke ọdọ mmiri a wụrụ awụ, ebe elu nwere. ọ dịghị ihe doro anya vaporization, ya mere ịgbado ọkụ nwere ike rụrụ.

Ngwunye ike nke laser laser nwere ike iru 10 9 W / cm 2. N'ihi oke ike dị elu, a na-emepụta obere oghere n'ime ihe ígwè ahụ n'oge usoro ịgbado ọkụ.

A na-ebufe ike laser na akụkụ miri emi nke workpiece site na obere oghere, na-ebelata mgbasa n'akụkụ na omimi njikọ nke ihe.

Atụmatụ nke ịgbado ọkụ laser:

1.   nnukwu omimi ngwakọta nke ihe, ọsọ ịgbado ọkụ, yana nnukwu ebe ịgbado ọkụ n'otu oge.

2.   Omimiri weld dị warara ma dị warara, obere mpaghara okpomọkụ metụtara, na nrụrụ ịgbado ọkụ.

N'iji laser iji kpoo PDC, nkwonkwo welded enwetara nwere ike dị elu, ruo 1 800 MPa, na ọ gaghị emebi oyi akwa diamond. Ọ bụ ezigbo usoro ịgbado ọkụ PDC, nke a na-ejikarị maka ịgbado ọkụ okirikiri okirikiri diamond.

Nnyocha na nkwalite nke PDC emewo ka ikike ịkpụ nke ihe ọkụkụ na ngwá ọrụ ma jiri ya tụnyere diamond eke, ọ nwere arụmọrụ dị mma. N'ịtụle ọrụ chọrọ na ọnụ ahịa PDC, enwere ike ịhọrọ usoro ịgbado ọkụ kwesịrị ekwesị.

Ọ bụrụ na ị nwere mmasị na ndị cutters PDC ma chọọ ozi ndị ọzọ na nkọwapụta, ị nwere ike ịkpọtụrụ anyị site na ekwentị ma ọ bụ mail n'aka ekpe, ma ọ bụ zipu ozi US na ala nke ibe ahụ.
