Model friction couple of MT1 tribological apparatus
Materials.
It is clearly visible on presented diagrams that frictional contact resistance begins to decrease (for all tested materials) after 600 s of examination, that is after applying of second load (producing pressure of 0.7 MPa value).
This testifies to these systems differentiation with regard to inclination to selective transfer phenomenon generation while level of resistance minimum value may testify to intensity of this phenomenon realizing by particular system of materials.

For the cladding materials, Fe-Al intermetallics have unique advantages due to their oxidation resistance, high-temperature strength, high-temperature hardness and relatively low cost [3].
So if the Fe-Al intermetallics can be utilized as coating materials, it will markedly improves the surface properties of the aluminum alloy.

Ship modeling procedure has three steps: gathering materials, orthographic views preprocessing, hull and weapons modeling.
Part 1: establish reference body 1) Establish a body, then a face on the top, let the plane and reference have same aspect ratio, make its length equals to the length of the ship, rename Top-Ref. 2) Open material editor, name the first material spheres Top-Reference-mat, click on the button “None” in transition color map channel, choose ship’s Top View, and set bitmap type in material/map browser. 3) Display map button, designate Top-Reference material to the plane to show image in the view. 4) Enable the button frozen objects for plane Top-Ref. 5) Select Top-Ref object in the left view, press Shift key and rotate the plane 90 degrees around Z axis, establish a new plane vertical to original body name Front-Ref. 6) Drag Top-Reference-mat to the next material window; rename Front-Reference-mat. 7) Assign ship side view in the transition color channel, Front-Reference-mat to object Front-Ref. 8) Move Front-Ref to the side of Top- Ref, and leave a space for model. 9) Similarly, establish
(a) generate lofting line (b) lofting (c) hull modeling (d) weapons modeling (e) combine hull and weapons (f) assign materials and textures Fig. 8 The whole ship modeling Conclusions Complex objects modeling on 3ds MAX platform needs to full consider the characteristics of the objects, flexible using of support software to preprocessing the original images, such as the line graph, orthographic views, etc.

Kabeel et al. [3] presented a detailed review of solar still enhancement strategies, focusing on phase change materials and reflective surfaces as key factors in improving distillation productivity.
In 2003, Fath et al [9] identified the potential for optimization in solar desalination systems through design modifications, such as multi-effect distillation and the use of advanced materials.
Al-Hinai et al. [21] found that the double-effect solar stills showed higher productivity compared to single-effect designs, particularly when optimized for temperature gradients and cover materials.
