The effects of Fe in ferrotitanium and pure iron on the reaction between ferrotitanium, carbon and iron during spraying are different.

理论上Fe-Ti-C系在反应火焰喷涂过程中存在许多反应，如氧化、氮化、碳化等，但Ti与C的放热反应是最主要的，其反应过程逐步进行。

According to the deterioration mechanism of concrete, the model of life perdiction in the corrosion form of corrosive medium and high heat were based on the penetration of chloride with the rustiness of steel and the carbonization of concrete with the rustiness of steel. The calculation results of service life of the origin concrete and new mending materials were close to the actural phenomenons.

根据两种腐蚀形式的劣化机理，建立以氯离子渗透和钢筋锈蚀以及温度影响下的混凝土碳化和钢筋锈蚀为主体的钢筋混凝土使用寿命预测模型，并分别对原有材料和新修补材料进行使用寿命预测，预测结果与实际工程相吻合。

A special process named " silicification followed by carbonization" was adopted to solve the problems such as SiC grains forming on the SiO_.

通过"先硅化再碳化"的工艺方法可以较好地解决S iO2/S i复合衬底上S iC成核困难以及粘附性差的问题，同时还可以有效抑制S iO2中的O原子向S iC生长膜扩散。

A special process named "silicification followed by carbonization" was adopted to solve the problems such as SiC grains forming on the SiO2 and poor cohesiveness between the SiC and substrate. Furthermore,this method is effective to prevent O atoms diffusing from SiO2 into SiC epilayer.
