Faamatalaga oloa

pine o oloa

ofoina Ningbo De-Shin se anoanoai o ario tungsten mo fanua eseese talosaga tau alamanuia. E manaomia ai le alualu i luma infiltration lagona gaogao faagasologa ma oloa uma feiloai le criterion o GB / T8320-2003, ASTM B631.

O Oloa Gaosia faagasologa: fefiloi efuefu -> fetaomi -> sintering -> infiltration lagona gaogao -> machining -> QC. E matua pulea uma lenei faagasologa tuuina e QC ina ia mautinoa ai le faatinoga lelei e sili ona lelei.

lelei:

1. conductivity eletise Ese.

2. conductivity vevela Ese.

3. density Maualuga ma microstruction atoatoa laugatasia o mea.

talosaga:

1. soli matagaluega.

2. soli leakage Lalolagi.

3. soli matagaluega laiti.

4. tetee maopoopo electrode.

5. laei fuata tetee

tele oloa:
