2) Agronomic factors
3) Technological factor
The influence of different technological factors of gel casting(PH,deflocculant,solid content,forming temperature,initiator and catalyst) on viscosity and gelling time of Al2O3-SiC ceramic suspension is studied in this paper.
The result shows that grain size of cBN and raw material purifying treatment in vacuum are the main technological factors of PCBN wear resistance .
After studying effects of technological factors (vacuum degree, pattern density, pouring temperature, metallic static head, pattern thickness and coating permeability) on the mold-filling velocity of AZ91D Mg alloy in the EPC process, the influencing law of these technological factors on the mold filling velocity are obtained, and the influencing degree of these tech.
4) technical factor
Relationship between technical factors and physical performances of magnesiabased castable;
Therefore, the part machining models have specific requirements and feature which are different from the part design models, and many technical factors concerned with machining need to be considered.
5) technological factors
Effect of technological factors upon microwave properties of the Ba 6-3 x (Sm 1- y Nd y ) 8+2 x Ti 18 O 54 ceramic;
Main technological factors which affect YAG laser- MIG/MAG arc hybrid welding were generalized.
The γ-dendrite morphology and the effects of technological factors in gray cast iron are studied.
6) process factor
Analysis of process factors of AC FZ-TIG welding for aluminum alloy
The effect of various process factors on decarburization process in VD was studied by the model and the optimizing decarburization process in VD can be obtained.
The practice of large scale production showed that a slight fluctuation of process factors would cause quite obvious influence on the material quality of Shenlong car camshafts.
