The bimetallic parts for auto-vehicles, type hypo eutectoid steel - alloy CuNiAl can be hardened by ageing heat treatment with a view to increasing the wearing resistance. Following this treatment, an intensifying of the process of precipitation of the chemical components that lead to the deposited layer hardening takes place. In order to spotlight these component elements, we have utilized a modern method of analysis of the bimetallic layers –

Alignment of the manufacture technologies to the environment European directives requirements represents a modern approach of the environment issues considered as integrant part of the lasting development which will represent one of the connecting ways of the Romanian economy to the globalization process. In the present work a pertinent study is made regarding the harmonizing into the limits imposed by the environment European directives (Dir. 99/13/CE,

The work studies the orientations regarding the recycling of the products from the industry of auto-vehicles parts and components, orientations that can provide solutions which permit to the enterprises producing auto components the efficient management of the related products and services during the whole life cycle of the products, from the conception phase to that of recycling. The new way of approaching the development of metallic auto products

The actual tendencies of the European market of metallic component parts for auto vehicles impose the utilization of materials that lead to the increase of the products reliability and their framing into the matrix cost-quality imposed by the big European producers [4,9]. The covering of the quaternary alloys based on copper with polyester is inscribed among the technological procedures that aim at the improvement of the performances of the metallic

The improvement of the life of the metallic products management in the industry of auto components has as a purpose to provide solutions which will allow the producers enterprises of auto components the efficient administration of the products and services during the whole life of the products, from the conception phase until the recycling one. The new way of approaching of the development in Romania of the metallic products for automobiles, promoted

The actual tendency in the world is to use the quaternary alloys in electro technique and electronics as springs, elastic elements good conductors of electricity, as well as in electric welding under pressure in points. In the literature of specialty there is no data regarding the behaviour of these materials in the heating process. From here our interest for the study of the electric resistivity of the quaternary alloys in the heating process appeared.

Alignment of the manufacture technologies to the environment European directives requirements represents a modern approach of the environment issues considered as integrant part of the lasting development which will represent one of the connecting ways of the Romanian economy to the globalization process. The work spotlights the new way of approaching the products development within the context of the bitter confrontation between the idea of profit,

Article highlights the need to adapt motivation and management style in the innovative process. The need to evaluate and adapt management style and motivation involved in the definition of enterprise for sustainable development, that production and products to the principles of zero-loss and zero pollutant emissions. Adapting motivation and management style follows highlighting possibilities of correlation between innovative process- motivation system-system

Technology for manufacturing light automotive parts (bearings, bearing boxes, spindle, bushings etc.) of bimetallic semiproduct parts obtained from liquid phase,replaces the classical manufacturing options for light automotive single cast parts made of alloyed steel or non-ferrous materials, with a technological version in which phases and operations rely on parts made of different materials in multilayer version, and which can be realized with minimum

The work studies the possibilities of metallic materials hardening, especially carbon steel and low alloyed steel, presenting the novelty elements related to the technological procedure, experimental installation, and study of quality, study of thermal processing, with a view to obtaining and determining the characteristics and structure of the superficial layers, the influence of the main metallurgical and technological factors.
