The article found that the corrosion rate of diffusion of brass alloys in an acidic environment reduced with increasing of zinc content in the coatings. High protec-tion can have 14 ÷ 20 at.% Zn
In the general complex of mechanized works when
growing potatoes, potato harvesting is one of the main
operations. The efficiency of potatoes growing at the
farm largely depends on harvest quality and crop
retrieval. When harvesting potatoes with potato
harvesters their productivity largely depends on the
state of potato haulm. In a case of evolved and laid
haulm the harvesting machines productivity falls
sharply due to working organs clogging and in some
cases their work is not possible at all. Therefore, to
facilitate the work of potato harvesters it is necessary
to remove potato haulm before harvesting. But the
process of haulm removing is very laborious, including
several operations, such as mowing, raking and
transportation, each of which is performed by a
separate machine. The appearance of domestically
made rotary-type machines like KIR-1.5, UBD-3 and
BD-4 at the end of 1950-1960 made it possible to
mechanize the harvesting process of potato haulm. But
it was noticed in the operation that rotor machines
have a number of drawbacks caused by imperfections
in the rotor design, its kinematic regimes, lack of
balance and some others. Therefore, studies aimed at
improving the design of rotary-type machines seem to
be very important. To achieve this goal some
theoretical and experimental studies and lab and field
tests of the modernized four-row shredder have been
carried out. When studying methods of mathematical
analysis and elements of classical mechanics were
used. Some modern methods were applied in the lab
and field tests. The modernized haulm shredder BD-4
was tested at JSC “Avangard” in Ryazan district
In this article, contact conditions are investigated at superficial plastic deformation by running-in rollers of details by a method of load cells
The description of crusher of potato tops with the variable diameter of cutting is given in article. Theory of planning of experiment, the dynamics of joint knives and laboratory-field tests of crusher are also considered
In the article, it is established that in the market conditions of economic recession of repair production, the traditional technological decisions focused on mass and business lot type, have lost the practical importance. Increase of the efficiency of drawing of wearproof coverings with the electropulse way is based on the use of technological possibilities of the way and the principles of technical self-sufficiency of small repair shops. For that, the combined way of processing, replacing use of the traditional technological equipment, with obtaining quality comparable to the existing technologies has been developed
The influence of a superficial plastic deformation and a corner of installation of a roller on the diagram of specific normal pressure and contact forces of friction is shown in the article
