Several attempt have been proposed to improve the properties of metallic interconnects by alloying [4].
The aim of this work was to deposit Co-Ni based coatings on AISI 430 ferritic stainless steel by thermal spray technique.
The feedstock powder consists of Co and Ni alloys was carried out by oxy-acetylene gas to the flame spray thorch and highly deposited onto the surfaces, to produces Co-Ni mixed layer.
The presence of Co and its compound were not detected by XRD.

The aim of this study is to investigate and optimize the friction stir process to produce localized particle reinforced zones in cast aluminum components.
The grey color represented the aluminum base, and those larger lighter particles (~2 μm) were Al-Cu compound precipitations that were broken up during FSP.

The microstructure of the MZ in a joint is strongly affected by two phenomena occurring during solidification, i.e, dendritic growth and solute partitioning, with consequent formation of carbides, borides and other metallic compounds.
Low melting compounds may give rise to micro-cracks after post-welding heat treatments [10] and local residual stresses arise in the MZ which can induce the failure of mechanical parts [11-12].

The Fe-O functional group, which is a characteristic of magnetite compounds, is at wavenumber 752 cm-1 [16], [17].
In this study, the aim of adding the PEO/PMMA has been used to control the stabilization of particle size and control the design of the crystal structure still on the octahedral structure [23].

Evaluation of the Possibilities of Processing High-Alloy Corrosion-Resistant Steels During Grinding Operations Andrey M.
The problem of abrasive processing of high-alloy corrosion-resistant steels and heat-resistant alloys is especially acute [6].
The presented work is aimed at studying the key parameters of processing with grinding wheels by the method of centerless cylindrical grinding.

The aim of this research is to investigate the impact of temperature on the IPs growth and formation mechanisms, completing previous works on microstructure and kinetics characterization of IPs in Al/Ni system at 720°C.
Introduction Investigations into new alloys and processes stem from the need for developing new materials, processes and selection strategies to satisfy more demanding service applications and environmental restrictions.
Due to potential technological applications, intermetallic compounds have attracted much attention in recent years.

Table 2 Chemical composition of two variants ALLOYS NO.
These alloys are called martensitic because they are capable of developing a martensitic structure after quenching from high temperature.
Precipitation hardening steels by virtue of their composition have excellent combination of strength and toughness, since the strengthening is due to precipitation of coherent intermetallics compounds.
These alloys require precision control of processing parameters in order to realize reproducible structure and properties.
The evolution of microstructure in a complex alloys is a function of the way the material is processed.

The most perspective components of the structure of this material is titanium carbide (TiC), characterized by high hardness, and heat-resistant nickel alloys as a metallic binder of carbide particles.
The aim of this work is to evaluate the wear resistance of products after arc welding using electrods made of powder SHS-mechanocomposites.
At the same time, the structure of welded metal during the complex process of alloying a prepared compound of titanium carbide ensures high wear resistance and hardness of the alloy as compared with a separate TiC introduction [9].
