Method of Risk Assessment Based on Ergonomic Criteria. Case Study: Crane Maintenance Electrician Vasiliu, Adrian; Bordei, Marian This paper presents a case study on the evaluation of a job (electrical maintenance) in AMG plant through a less used method in Romania, respectively Renault method, used especially in France. Means of work are analyzed on the basis of the technological equipment, the work task based on the job description and the work medium based on analyzes of made by occupational medicine. The test results are tabulated and graphically processed and they are taking into account to establish the conclusions and the measures to be imposed at the analyzed work place.

The paper focuses its attention mainly on titanium and titanium alloys, even though there are biomaterials manufactured from other metals, ceramics, polymers and composite materials. Both electrodeposition and anodic oxidation surface modification methods are discussed with several examples and a brief description of underlying theory, in order to improve the mechanical, chemical and biological properties of these materials.

This powder perform several important functions, such as thermal insulation, protection against liquid steel surface oxidation and capturing inclusions from the bath. This paper presents an experiment carried out with an acid powder based on thermal power plant ash to the casting of steel with carbon content from 0.30 to 0.33% and 1.00 - 1.15% manganese. Powder behavior during casting can be summarized as follows: rapid spreading of liquid steel surface, good thermal insulation, revealed by the gradient temperature from the slag. The average specific consumption recorded was very low, 0.4 kg / t liquid steel. It has been analyzed the chemical composition of the slag from the tundish during casting, to prelevate 6 consecutive samples taken during casting. The compositions of these slags were compared to the oxide powder composition initially given on the liquid steel. There was a good absorption of inclusions, as evidenced by the last composition of the analyzed slag sample. There was a strong increase of MnO content and changes in values of the other oxide compounds, such as SiO2. The paper highlights the experimental slag capacity, a hard acid slag based on thermal power plant ash, to capture the MnO type inclusions, up to 38%. This process can be interpreted as negative, meaning that the acid slag is absorbed from the steel alloying element, manganese.
