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)于熱梯度化學(xué)氣相過程中預(yù)制體致密機(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)制體表面孔隙過早堵塞的現(xiàn)象，適合制備軸對(duì)稱的環(huán)形、管型件。
