How to restore parts of the car

The main goal pursued by all the maintainers, this reduction in the cost of repair of cars and components. The study of repair fund showed that on average about 20% of the parts are scrap, from 25% to 40% are usable, and the remaining 40-55% can be recovered. Even the percentage of scrap parts can be significantly reduced if the use of effective methods of fault detection and recovery of parts and units of the automobile. Recovery technology parts of the car belongs to the category of the most resource, it is mainly connected with the fact that, compared with production of new parts to cut costs significantly. The most basic source of savings is the cost of materials. The average cost of materials in the manufacture of parts make up 40%, and in restoring 6% of the total cost of the product. In order to recover completely worn out parts required is 5 times smaller manufacturing operations compared with the manufacture of new parts. Despite this efficiency, the complexity of the restoration of parts is unreasonably high. The main number of failures caused by wear and tear of car parts of their working surfaces, this number reaches 50%, 17% failure rate is related to injuries and about 8% of failures caused by cracks. Main place of all the failures of car parts is the vehicle's engine, it involves 45% of all failures of parts. About 85% of all worn parts restored during wear of 0.3 mm, and their full efficiency is restored when applied to these coatings of small thickness. Application of metal-bearing surface with a machined piece allows you to reuse. To date, the company repairs and service stations in Moscow are a sufficient number of ways to repair parts, each of which is tested in practice. Such methods include methods of repair of sizes, additional parts, plastic deformation, elektoliticheskih and gas thermal coating. However, not all of the above ways to repair parts are equal. Using the method of repair many times the size of the system is complicated by the supply of spare parts, begins to emerge is the need for large inventories of parts with different nomenclature. In addition, repeated use of this method leads to a significant reduction of safety components, the partial reduction of their durability, it is particularly connected with the fact that this method of gradually removed many different ways reinforced upper layer of metal. With partial use way more details to a great extent increase the cost of a full recovery products and this, more so in the end leads to the fact that this method is economically disadvantageous. Particularly disadvantageous to use such a method of restoring the parts that have slight wear. The easiest and one of the most economical way to plastic deformation has a limited area of ??application, and often can not be used to restore any specific product, it is connected with specific features of their basic design. To all of the existing methods of coating to choose more efficient, you need to properly and carefully evaluate their own coverage, and their applicability to restore each individual part. The performance of each particular method is determined by the amount of time spent on pre-processing of each product in the recovery process and further mechanical processing of the product.
