摘要： The invention relates to a method and a device for laser-beam welding, because the invention is especially suitable for deep welding a wide variety of materials. The object of the invention is to weld a wide variety of materials by means of laser radiation, especially by deep welding, with a reduced amount of work and at the same time good quality of the welded joint produced. The procedure adopted for this according to the invention is that the intensity of the laser radiation is set by beam-shaping in and on the surface of workpieces in such a way that a small area in the workpiece is irradiated with a great intensity, to form a steam capillary there, and a further, larger adjacent area on the workpiece surface is irradiated with a lesser intensity, and as a result a bell-shaped opening of the steam capillary is formed on the workpiece surface and the cooling rate of the melted material is reduced.

摘要： The invention relates to the hardening of the surface layer of parts of machines, plants and apparatuses and also tools. Objects for which the application is possible and advantageous are components which are subjected to severe fatigue or wear stresses and are composed of hardenable steels and have a complicated shape and whose surface has to be hardened selectively on the functional surfaces or whose functional surface has a multidimensional shape. The process for hardening the surface layer of components having a complicated shape is carried out by means of a plurality of energy input zones. According to the invention, it is characterized in that the energy input zones are conducted on different curved parts separately in space and time and by means of cooperatively working transport systems so that superposition of the individual temperature fields forms a uniform temperature field which completely covers the functional surface of the component and within which each surface element of the later hardening zone of the component attains the selected austenite formation temperature interval ΔTa at least once and the time interval Δt between the maximum temperatures Tmaxn of the individual temperature fields is from 3.1 to 3.n smaller than the time ΔtmS which is required to go below the martensite start temperature MS during the cooling phase. The apparatus by means of which the process of the invention can be carried out is, according to the invention, characterized in that the energy configuring units are connected to one or more energy sources for optical or electromagnetic radiation and are each fixed to separate but cooperatively operating transport systems.

摘要： The invention relates to edge layer finishing of functional components, and thereby in particular to a method for producing wear-resistant and fatigue-resistant edge layers in titanium alloys, and components produced therewith. The method according to the invention for producing wear-resistant and fatigue-resistant edge layers in titanium alloys by means of laser gas alloying is essentially characterized in that the laser gas alloying is carried out with a reaction gas that contains or releases interstitially soluble elements in the titanium alloy used, whereby the partial pressure of the reaction gas is selected such that the partial pressure remains below the threshold value above which nitride, carbide, or boride titanium phases are produced. The features according to the invention of the wear-resistant and fatigue-resistant component made of a titanium alloy with a gas-alloyed edge layer essentially are that the wear-resistant edge layer is composed of a fine-grain mixture of α- and β-titanium grains with an interstitially dissolved reaction gas, has a surface hardness Hs, measured on the ground surface, of 360 HV0.5≦Hs≦500 HV0.5, or an edge layer microhardness HR, measured on a polished cross section at 0.1 mm below the surface, of 360 HV0.1≦HR≦560 HV0.1, extends over a depth tR of 0.1 mm≦tR

摘要： The invention relates to a wear-resistant, highly stressed and low-friction boundary coating construction for titanium or the alloys thereof which can be advantageously used in order to protect human implants. According to the inventive boundary coating construction the boundary coating is comprised of a 200 to 400 nm thick DLC coating (4), a 5 to 50 nm thick intermediate coating (3) and a 0.3 to 2.0 mm thick gas alloyed coating (2), said gas alloyed coating having a hardness between 600 HV0.1 and 1,400 HV0.1. The inventive boundary coating construction is produced by firstly melting the surface of the member which is to be protected. The surface is then gas alloyed and cleaned in an N2/Ar atmosphere. Subsequently, the intermediate coating is first deposited followed by a depositing of the hard amorphous carbon coating by means of the laser-induced, pulsed vacuum arc (laser-arc) method.
