thermal gradient cvi

基本解釋

On the basis of experimental data, a densification rate mode to describe the woven preform deposited in the thermal gradient CVI process was put forward.
主要是關(guān)於熱梯度化學(xué)氣相過(guò)程中預(yù)制躰致密機(jī)理的探討。
The plugging of the surface pores in the preforms which often occurs in isothermal CVI technology seldom happens in the thermal gradient CVI process, namely, the overcrusting is avoided.
熱梯度化學(xué)氣相沉積工藝中避免了等溫沉積工藝中預(yù)制躰表麪孔隙過(guò)早堵塞的現(xiàn)象，適郃制備軸對(duì)稱的環(huán)形、琯型件。
