Process schemes and factors improving adhesive properties and wetting quality of the fiber with the alloy are shown.
Moderate thermal effect, the kinetic pressure and other factors of external action can change distance between atoms within few percent and are unable to affect this discrepancy and, as a consequence, the surface energy and wetting quality.
All mechanical characteristics of the obtained samples are higher in comparison with the foundry alloy AlSi9Mg.

This, in turn increases the elastic compliance and plastic energy dissipation ability of the bulk solder, which are the key factors to enhance the drop resistance [9].
Thus, the aim of this study is to investigate the influence of Si3N4 particles addition on the microstructure, thermal behavior, and mechanical properties of SAC107 solder alloy.
It may be noted that with increasing quantity of reinforcement particulates into solder could affect the solder properties.

However, past research results [2] show that the properties of ZrB2 based composites are strongly dependent on processing.
The mechanical, thermal, and oxidation properties of the zirconium diborides, carbides and their composites with SiC reinforcements have been evaluated by Opeka et al. [4] and Monteverde [5].
The present study is focused on the microstructure, mechanical properties, thermal shock and ablation resistance, as well as isothermal and non-isothermal oxidation behaviour of the hot pressed ZrB2 based composites.

However, ATH starts to aggregate at high loadings, which will deteriorate system’s processing ability and mechanical properties. (9).
These two properties reflect the advantages of the orthogonal array: uniform dispersion and regular comparable.
In other words, any factor at each level is compared to all different factors at each other (26).
The higher the`Yjk is, the better effect of viscosity reduction of j factor has at k level, which can determine the priority level of the j factors, then find optimal combinations for the various factors.
The priority order of the factors is the same

Influencing Factors The preparation of bioglass by sol-gel method is not a complex course, but it is influenced by many factors.
Many factors can affect this process through the gelling time, which include the H2O dosage, ethanol dosage, pH, temperature, activator and so on.
Zhong et al. [21] discussed the processing and properties of sol-gel bioactive glasses.
The demand of material properties is more strictly, so the preparation of biomaterials should be more strictly.
