Abstract (English):
There are considered engineering methods for cutting-out punch life increase on the basis of laser processing operation surfaces, and also their laser alloying with different materials. The results of experimental investigations are shown which reveal potentialities of the methods under consideration from the point of view of dynamic surface strength and deformation durability increase. Practical recommendations on the introduction of the results obtained are given.

Keywords:
cutting-out punches; coatings; alloying materials; laser alloying; strengthening; dynamic durability; wear-resistance; life
