Yiziphi izinduku ze-tungsten carbide composite?

I-tungsten carbide composite rod yenziwe ngamathiphu e-carbide kasimende kanye ne-Ni/Ag(Cu)alloy. Izeluleko ze-carbide zihlale ziyi-tungsten carbide grits echotshoziwe, okokufaka kwe-carbide wear, njengokufakwa komumo wenkanyezi ye-carbide, ukufakwa komumo wephiramidi ye-carbide, ukufakwa komumo woshaka, njalonjalo. Ngezinye izikhathi, amathiphu carbide kungaba tungsten carbide powder. Inketho yezomnotho i-tungsten carbide grits echotshoziwe. Uma ufuna ukuqina okuphezulu kune-carbide grits, ukufakwa kwe-carbide kungcono. Kodwa-ke, i-carbide enosimende/i-carbide echotshoziwe enonqenqema olucijile inokumelana okuhle nokugqokwa nekhono lokusika futhi.

Ubulukhuni buyi-89-91 HRA, insimbi yokuhlanganisa i-Ni ne-alloy yethusi, amandla angafika ku-690MPa, ubulukhuni HB≥160.

Kafushane, izinti eziningi ze-Composite ezenziwe kusetshenziswa izinhlamvu ze-Tungsten Carbide ezichotshoziwe eziboshwe nge-matrix ye-nickel yethusi, (Cu 50 Zn 40 Ni 10) enephuzu elincibilikayo eliphansi (870°C).

Kungani usebenzise i-tungsten carbide grits njengento eyinhloko

Sonke siyazi i-tungsten carbide inobunzima obukhulu,I-Tungsten carbide inokusebenza okuhle ekusikeni kwensimbi.TI-ungsten carbide grits inezindawo zokumelana nokugqoka. TI-ungsten carbide grits ingavikela ingaphezulu lamathuluzi angaphansi kokuguga. Tamathiphu ungsten carbide raiseisivinini sokugaya nokusika i-downhole,ukugcina i-gauge egcwele kuzinzinzisi, izisusi zezihlalo eziyisihluthulelo zamagayidi, namanye amathuluzi okukhipha imbobo.

Amasayizi okusanhlamvu we-carbide grits:

1/8-1/16 in. ( 3.2-1.6 mm)

3/16-1/8 in. (4.8-3.2 mm)

1/4-3/16 in. (6.3-4.8 mm)

3/8-5/16 in. (9.5-7.9 mm)

5/16-1/4 in. (7.9 -6.3 mm)

3/8-1/4 in. (9.5-6.3 mm)

1/2-5/16 in. (12.7-7.9 mm)

Amabanga wezintambo ezihlanganisiwe

Amabanga amabili ayinhloko ancike ku-Proportions ehlukene yegrits ye-tungsten carbide

1. Ibanga lokusika:I-70% ye-tungsten carbide + i-binder engu-30%.

2. Ibanga lokugqoka :I-60% ye-tungsten carbide + i-binder engu-40%.

Ungakhetha amabanga ahlukene kuye ngohlelo lwakho lokusebenza.

Ingabe uyafuna ukwazi ulwazi olwengeziwe mayelana nezinduku eziyinhlanganisela ye-tungsten carbide nezinye izinto ezibheke kanzima? usithumelele i-imeyili [email protected].
