The article aims to investigate polymer inorganic composites for electromagnetic radiation absorption using potassium titanates.
Depending on synthesis conditions and chemical composition, PTT is either an amorphous compound with a layered (flaky) structure, or crystalline submicron- and nanofibers (potassium tetra-, hexa-, or octatitanate).

As-cast Al-Sc alloys and Zr-containing Al-Sc-Zr alloys were aged at 300℃ for different times, the Al-Sc-Zr alloy showed more excellent precipitation strengthening.
The peaking value of Al-Sc and Al-Sc-Zr alloys after aging was more than three times that of as-cast alloys.

Introduction
Titanium alloys are widely used in the aerospace, nuclear, chemical, biomedical industries and so on,
due to their excellent combination of low density, high strength to weight ratio, excellent corrosion
resistance and biocompatibility.
At same times, titanium alloys are recognized as a difficult-to-cut material [1].
However, some of them, especially extreme pressure additives, contain Cl, S or P compounds which endanger to environment and people health.

This thesis is aimed at obtaining wear-resisting-antifriction functional composite material by trying to improve the tribology performances of composite deposite through adding nano- Al2O3 and PTFE in the process of chemical deposition of Ni-P composite deposite.
Meanwhile, high content P enables the alloy to have high passivating ability, and strengthens the anticorrosion property of the Ni-P alloy plating.

The recent discoveries that aim to facilitate the routes for obtaining a high surface carbides led to rapid progress on the application of these materials in catalysis, hard metal alloys [5-7] and metal-ceramic composites [8-10].
The uniform distribution and fine particle size (nanostructured) phase reinforcement (TaC and NbC) added to the steel, allows a homogeneous dispersion of carbides in iron matrix providing a uniformity of properties, thus allowing the compounds to be use in a variety applications.

These compounds are capable of increasing the corrosion resistance of hot-dip galvanized steel in hydrogen peroxide (30%), concentrated sulphuric acid (98%), and phytic acid [17].
This result shows that the majority of corrosion products are FeO compounds, which are the sum of the mass element of Fe and O in each test.
