Thus, the aim of this study was to develop technological ways to increase the efficiency of a tool made of carbide and high-speed steel by improving functional coatings applied to the working surfaces of cutting tools.
Such compounds have extremely low ductility of crystal lattice, and that complicates progress of dislocations and provides WRC with minimal propensity to mechanical and thermal activation, reduces the tendency of wear-resistant material to adhesive interaction with material being machined.
Therefore, in selection of the composition of external layer of WRC, preference was given to the most hard and refractory compounds containing maximum SWACS of sp3 type (materials with predominantly metallic bonds), s2p6 (materials with mixed types of bonds) and d5 (materials with covalent and ionic bonds) alloyed Al and Si.
As adhesion component of WRC, compounds with metallic bonds (transition refractory metals of IV group or their nitride and carbide compounds) were used, and for intermediate components of WRC  inert compounds with ionic and covalent bonds were used.

Paper title Journal Year Ref.
Cluster Description Keyword density Strength of the link Cluster 1 (green) “Microstructure” is highly related to laser technologies, alloys, and heat treatments.
This implies that there are journals whose publications have had a much greater impact compared to other journals.

The paper shows very good results obtained to FSP processing (for cast aluminum alloys), to friction riveting with hybrid effect (for aluminum and copper alloys) and to friction riveting (for aluminum alloy), but also some limitations of these friction processing methods.
ISIM Timisoara has also addressed the issue of surface coatings with functional alloys made of lightweight alloys (aluminum alloys), on steel substrates (S 235), by using the FSW process with consumable tools (national research project 72174/2008-2011 TIMEF, carried out within the PNCDI II Partnerships Program), also having a patent application for the constructive solution and characteristics of the consumable tool (patent application no.
Based on the experience gained in processing of this material, complex researches were also carried out for FSP processing of the following types of materials: - cast aluminum alloys: AlSi12 (4047); AlMg4.5Mn0.7 (5083); AlZn5.5Mg1.5 (7021); - other aluminum alloys - AlSi1MgMn (EN AW 6082) and AlZn5,5MgCu (EN AW 7075); - copper alloys (CuZn31Si brass and CuSn10 bronze); - X5 CrNi 18 10 stainless steel (AISI 304).
Deposition of functional layers from lightweight alloys on steel substrate.
The use of the SFSW underwater welding method aims to obtain advantages over FSW welding: avoiding overheating of tools and of materials to be joined during the welding process, with the scope to obtain a finer grained structure and thus better mechanical properties, reducing the development of the intermetallic compounds, of the residual stresses and deformations at welding, as well as reducing of welding defects.

In light of the above, the present investigation is aimed at assessing the slurry erosive wear behaviour of aluminium based MMCs with high volume fractions of SiC developed by an innovative hybrid process. 2.
A reduction of 51.47% in weight loss when compared with matrix alloy is observed.

Mechanical properties of PAMCs are inferior compared to whisker/short fibre/continuous fibre reinforced AMCs but far superior compared to unreinforced aluminium alloys.
Consequently, it can be used to produce alloys and compounds which are difficult or impossible to be obtained by the conventional melting and casting techniques [11].

The polyol process consists of the reduction of metallic compounds such as oxides and salts in a liquid alcohol medium maintained at its boiling point.
In order to remove the TTEG and partial organic compounds, the resulting solution was washed several times with acetone.
However, the actual aim of preparing the nano crystalline sized LiFePO4 material is fulfilled.

These assay-samples have been sectioned for the aim of determining the hardness on each section and researching the resulted microstructure.
This decrease of hardness is caused by the precipitation of some secondary chemical compounds and the relaxation of internal stress from the γ solid solution.
The chrome from the deposited alloy diffuses in the base material and the carbon atoms from the base material form pearlitic colonies in the deposited alloy, in the transition area.
