(1) Lub log nrawm. Qhov sib tsoo log nrawm rau kev sib tsoo high-kub alloys feem ntau yuav nyob ib puag ncig (20 ~ 25) m / s. Raws li
Cov ntaub ntawv yuav tsum qis dua 20m / s kom txo qhov adhesion ntawm kev sib tsoo log thiab txo qhov kub sib tsoo. Qhov ceev ntawm cubic boron nitride sib tsoo log yog (30 ~ 35) m / s.
(2) Ua haujlwm ceev. Cov haujlwm ua haujlwm nrawm muaj qhov cuam tshuam zoo rau qhov sib tsoo hlawv. Rau cov khoom siv hluav taws xob kub nrog cov qhov siab thiab qhov tsis tshua muaj thermal conductivity, qhov kev ua haujlwm ntawm qhov nrawm yuav tsum tsim nyog nce kom txo thiab kov yeej qhov tshwm sim hlawv. Txawm li cas los xij, qhov kev ua haujlwm siab yuav tsum tsis txhob siab dhau, txwv tsis pub nws yuav ua rau tus kheej muaj kev vibration. Thaum lub voj voos sab nraud thiab sab hauv yog av, qhov chaw ua haujlwm tawm ceev yog li 30 m / min. Lub rooj ceev thaum lub sib tsoo saum npoo yog (25 txog 28) m / min rau kev sib tsoo ntxhib thiab (15 txog 25) m / min rau kev sib tsoo zoo.
(3) Cov nqi pub noj. Nws qhov loj tau loj yoog nyob rau saum npoo roughness ntawm kev sib tsoo. Kev pub ntev ntev thaum sib tsoo sab nraud
Tus nqi yog (0.05 txog 0.5) Bmm / r, thiab tus nqi yog me thaum zoo sib tsoo. Qhov pub ntev pub thaum lub sij hawm sib tsoo sab hauv yog (0.1 txog 0.3) Bmm / r; qhov pub pub rau tom qab thaum lub dav hlau sib tsoo yog (0.4 txog 0.6) Bmm / dst.
(4) Sib tsoo qhov tob. Qhov sib tsoo qhov tob thaum sib tsoo cylindrical yog (0.01 ~ 0.06) mlTl, thiab kev sib tsoo sab hauv yog (0.01 txog 0.05) hli, dav hlau sib tsoo yog (0.01 txog 0.05) hli. Siv tus nqi loj thaum ntxhib tsoo.
(4) Sib tsoo nyiaj pub. Qhov sib tsoo tso cai ntawm superalloys yuav tsum me dua qhov ntawm cov khoom siv sib tsoo no kom txo cov khoom sib tsoo.
