Introduction With the development of missile weapons, new material and manufacture technology continue to merge, and a number of breakthroughs are seen in the area of isolation thermal materials.
Composite materials are considered high specific strength and modulus, highly resistant to high-temperature, ablation and impact, therefore it is being widely used in astronautics and aeronautics industries, replacing the traditional materials such as ferrous and non-ferrous metals and dominating the materials for thinner and thermal-resistance structures.

DDTs are associated with organic materials of surface coatings via chemical bonds.
The changes of constructions of organic materials were not conducive for DDTs to confine with organic materials, which influenced desorption of DDTs from surface coatings.

In Situ Synthesis of a Wear Resistant Layer on the Surface of Low Carbon Steel Produced by Laser Melt Injection Technology Valéria Mertinger1,a, Gábor Buza2,b, Balázs Major3,c 1Institute of Materials Sciences, University of Miskolc, 3515 Miskolc-Egyetemváros, Hungary 2 Institute of Materials Sciences and Technology, Bay Zoltán Nonprofit Ltd., Budapest, Hungary 3Institute of Enzymology, Research Centre for Natural Sciences, Hungarian Academy of Sciences, 29 Karolina str.
Titanium and its compounds are one of the most frequently used reinforcing particles in iron – ceramic composite materials.
These materials have special characteristics because they are quenchable, their hardness can be increased by heat treatment and they can be quite easily machined.
The point of the technology developed in the Bay Zoltán Institute of Materials Sciences and Technology is to form the reinforcing layer on the surface of the sample in an in situ way by melting the surface of the low carbon steel and the laminar carbon felt using laser beam while the titanium metal powder is simultaneously added to the melt.

However in case of a heterogeneous material model, the identification procedure has to be able to quantify the aleatory uncertainties capturing the variability of the material properties.
This contribution concentrates on identification of aleatory uncertainties in the context of heterogeneous materials, their character causes spatial variations of mechanical parameters (such as elastic modulus, yield stress or tensile strength) affecting the structural system behaviour under the loading.

The results showed that, peripheral speed and load had significant effects on wear resistance of materials.
In this study, gray iron, which is the main material of alfalfa lawn mower wheel, and loess were chosen as sample materials to study the abrasive wear behavior at different speed and load condition by abrasive wear testing machine.
