Opis:: Earlier researches have proven that sliding bearings cooperating with different surface layers of s have shown different wear. There is also a difference between cooperation characteristics, which can be measured with help of different electric potential (GRP) in sliding couple. Analyzing changes in characteristics of generated potential difference effective value u s-grp during operation allows to estimate time Tg since the beginning until to forming of oil wedge shows up and estimate time Ts — says about stabilization tribological processes infrictional contact (running-in process was finished). This work will present the investigations results of s surface layer structure influence on the size of wearing of cooperating bearing and the characteristics of this cooperation. It has been proven, that there is a definite impact of a phase structure; with a good probability it became clear that grain size and placement and size of different phases also provided some impact on cooperation of pivots and bearings. Considering pivots covered with clear metallic coating, there have been proven impact of the type of metallic coating, macrostructure (density of crack mesh) have also been proven to be very influential.

Opis:: In earlier investigations it found that in lubricated sliding couples is generated electrical potential difference (GPD). The sensitivity of this tribological index and information quantity contained in it far exceeds than previously used (classical) indicators, like coefficient of friction or temperature. Previous investigations do not allow to draw generalizing conclusions, how the force of the tribological parameters affect the GPD signal value. Selected materials of samples and counter-sample were grouped in pairs, forming various combinations I - the same name materials couple, in which the sample and counter-sample were made of the same material; II - the various name materials couple, in change places pairs, in which the two different materials interchangeably in one case are the samples and the second - counter-samples; III - the various name materials couple, in change places pairs, in which the sample from one material was mated with counter-samples from different materials. The testing materials were selected associations represented by a series of metal lying in the Volta electropotential (galvanic) series, both relatively close to each other, as well as a considerable distance and some of the same metal alloys. In presented investigations it was state that there was no clear relationship between the recorded GPD signal effective potential value and the values of the electropotential (galvanic) series. The GPD signal value is individual feature of the each couple and depends on the type of construction materials each pairs of elements forming the each couple. The GPD signal value is lower for the same name materials couple, in which the sample and counter-sample were made of the same material, than for various materials couple. It was found that in the various name materials couple, in which the two different materials interchangeably in one case are the samples and the second - counter-samples, GPD signal value is different.

Opis:: This paper presents the results of operational research into the piston-cylinder liner system of marine combustion engines used for ship propulsion. According to research, there has been the identification of damages of the following elements: piston, piston rings, and the cylinder liner unit. In this article, there also has been made an effort to specify favourable conditions for the appearance of individual wear type.

Opis:: W pracy zaprezentowano wyniki badań dotyczące składowych zużycia całkowitego przeprowadzonych w warunkach modelowych. Na drodze obróbek cieplnych i cieplno-chemicznych zmodyfikowano stan warstwy wierzchniej próbek otrzymując inne charakterystyczne dla każdej z obróbek własności warstwy wierzchniej. Następnie otrzymane próbki poddano zużyciowym testom ścierno-korozyjnym i oszacowano składowe zużycia całkowitego.
The paper presents results of total wear constituents of modelled elements in friction nodes. Using heat and thermochemical treatment, the condition of surface layers in samples has been modified, and alternative properties of surface layer, characteristic for different treatments, have been arrived at. Then, the samples were put to abrasive and corrosive wear tests.

Tytuł:: Physical aspects of application and usefulness of semi-Markovian processes for modelling the processes occurring in operational phase of technical objects

Opis:: In the paper usefulness of semi-Markovian processes for modelling real processes which occur in the operational phase of various technical objects, is considered. The usefulness of this theory was proved by presenting specific features of the semi-Markovian processes and physical aspects of their use as models of the processes occurring in the operational phase of the objects in question. The specific features were described with taking into account the process of changing the technical states of such objects. The physical aspects of models in the form of semi-Markovian processes were justified by postulating a hypoŹthesis by which wear process of tribological units of crucial sub-assemblies of machines, can be explained. Also, the consequences logically resulting from the hypothesis and necessary to its verification, are discusŹsed. A method for its verification is also attached. It was proved possible to model the real processes in question by means of the continuous semi-Markovian processes of finite set of states.
