-The work presents the results of comparative chemical and thermal processing analysis of components at one of the small enterprises of the Central Black Earth Region and one of the plants in France. The modern examination equipment allows carrying out the metallographic studies more accurately, developing the metallographic specimens with a high quality surface under study that was impossible to achieve 10-15 years ago. It makes it possible to improve the quality of components produced by small enterprises and to raise their degree of cooperation with parent enterprises to a higher level.
