New Installation for Electro-Spark Alloying


Installation of electro-spark alloying of metal surfaces «ПЭЛ-28» is intended for enhance of wear resistance and recoveries of sizes of worn-out parts of machines and press tools, a reinforcement of cutting tools and machining attachments, coating of noble metals and alloys on electric contacts. Can be put as alloys (WC, TiC, VC, etc), and pure metals (Ni, Co, Cu, or Al alloys).

Main characteristics:

  • Maximum thickness of coating - up to 0.4-0.5 mm
  • Efficiency - up to 3-5 sm2/min
  • Power - from 0.3 kW
  • Weight - from 9 kg

Main Advantages of Installation

Results of electro-spark alloying:
- Recoveries of sizes of the outweared mounting surfaces of details and increase service life in 3-4 times
- Time increase between resharpening and working life of cutting tools (metal-cutting or woodworking) in 5-8 times

Main Advantages of Process

1. Locality of treatment of surfaces, minor heating of a detail, and possibility of formation of demanded operating characteristics of surfaces, high cohesive resistance of covering with the basic material.

2. Economy of material resources at the expense of: increases of wear resistance of workpieces and restoration of working surfaces, decrease of a time of their repair and service, increase of time of between-repairs work of equipment.

Simplicity and mobility of installation allow to use it directly on work place, thus from the personnel high qualification and long instruction is not required.

Areas of Application

Installation can be claimed on:
- Machine-technological stations
- In repair manufacture
- At the factories of heavy engineering industry, easy and process industry
- In electric power industry, etc.

Stage of Development

Tested, available for demonstration – field tested. Installations can be made under parameters of the customer.
