Approximately 90% of all metal surfaces are coated and factors such as the composition, the application processes and the possibility of combining organic and metallic paints have increased the interest of this type of coating for corrosion protection [2,3].
Use of epoxy resins is widely spread mainly due to properties such as continuity, flexibility, excellent adhesion to metallic substrate and chemical resistance in various aggressive environments.
The environmental condition to which the material is exposed is one of the factors that most influence the corrosion process.
Other factors such as pH, temperature and mechanical stress to which the exposed material could be subjected to should also be considered [6].
Evaluation of corrosion resistant properties of the coating by EIS and OCP studies To evaluate the efficiency of the coatings against SAE 1020 carbon steel corrosion, electrochemical tests were performed, such as Open Circuit Potential (OCP) and Electrochemical Impedance Spectroscopy (EIS) using an aqueous solution of 3 wt% NaCl to simulate the marine electrolyte.

In thermal and mechanical analysis of this study, many factors such as the actual element birth and death, the flow of the liquid in the weld pool, the strain history of the weld metal were taken into account.
Based on the accurate calculation of other factors, phase transformation was considered through setting the thermal strain depending on temperature.
The material data of thermal physical properties and mechanical properties referred to Eurocode 3 [8].
Weld and base metal were assumed to have the same composition and properties.
On the effect of welding thermal cycle, the HAZ has uneven microstructure and properties.

This robot adopts four tracks composite drive mechanism with front and rear machine hinged, and has good climbing, obstacle capability, the ground adaptability, mechanical properties, waterproof, fireproof, explosion-proof and other functions.
It carries oxygen, food, lighting, water, self-help equipment and first-aid medicines to achieve effective relief. 1 Introduction Due to many factors, the coal mine accidents are frequently occurred in our country.
With high transmission efficiency and better technology in mechanical transmission, the robot should have small section size (1000 * 280 * 250).
So it is highly flexible and not affected by resistance in the front or the side of the machine.

SLM is a promising technology that offers many advantages in terms of mechanical properties and density [4].
According to Bartolomeu et al. [5], 316L stainless steel components produced through SLM have shown higher mechanical properties and tribological performance than parts created by conventional technologies.
Therefore, studying the single-track formation mechanism in accordance with process factors such as LP and speed is very decisive.
· Properties of material including density, specific heat and conductivity are temperature dependent.
The thermal properties of the Ti-6Al-4V are shown in Table 1.

During all these processes, the major mechanical positions of the main unit structure showed in figure 2(b).
The draw ratio of rollers mainly affects the inflexibility,the bigger the draw ratio is, the worse the inflexibility is.
Based on the above-mentioned factors, the average velocity of calendering is 43m/min during the calendering process.
The speed ratio of this machine is mostly related to calender method and material property.

In conclusion, the determination of the possible applications of the technology in practice after changing the properties of the material around the hole.
Distance from basic material Flowdrillových holes and heat-affected zones shows a typical single-phase microstructure of austenitic stainless net polyhedral twin austenite grain boundaries.
Grain edges were only sparsely detected during etching, showing very low carbon content and a negligible margin granular carbide settling in the heat affected zone as a result of thermal effects of thermal drilling process Flowdrill, Fig. 5.
Structure change takes place gradually from the edge of the hole to 3mm, and very significantly, up to 8mm from the edge of the hole is still changing properties.

This paper evaluates the effect of the installation process on the mechanical and hydraulic properties of non-woven geotextiles.
The changes occurred in the properties of the geotextiles were evaluated by mechanical and hydraulic tests.
The mechanical actions that geotextiles are subjected during the installation process can cause unavoidable changes in their physical, mechanical and hydraulic properties.
However, in most cases, the damages are only assessed in terms of mechanical properties (often by tensile tests).
Thus, the effects of DDI in the mechanical properties are less pronounced for geotextiles with higher mass per unit area.
