Abstract

The invention provides a Gcr15 material surface strengthening treatment technology and device and belongs to the technical field of metal surface treatment. The problem that the surface anti-fatigue performance of an existing Gcr15 material part surface is poor is solved. The Gcr15 material surface strengthening treatment device is composed of a well type furnace, a gas supply device and a coolingdevice. The well type furnace is composed of a control panel, a furnace shell, and a furnace cover arranged on the top of the furnace shell. A hearth, a furnace tank and a material basket are arranged in the furnace shell. The hearth is filled with a heat preservation and heat insulation layer, and a heating element is installed on the inner wall of the heat preservation and heat insulation layer. Multiple thermocouples with the end portions stretching in the furnace tank are arranged on the furnace cover. The furnace cover is provided with an ammonia pipe, a nitrogen pipe and a dioxide carbon pipe. The Gcr15 material surface strengthening treatment technology includes the steps that cleaning drying is conducted on a Gcr15 material through argon ion sputtering for 30 min, drying is conducted, then the Gcr15 material is put into the well type furnace to be heated to 250 DEG C to 300 DEG C, then temperature is increased continuously, and when the temperature is increased to 480 DEG C to500 DEG C, ammonia and carbon dioxide are led in. By means of the Gcr15 material surface strengthening treatment technology and device, the surface wear resistance and the anti-fatigue strength of the Gcr15 material can be improved.

Description

technical field [0001] The invention belongs to the technical field of metal surface treatment, relates to a Gcr15 material, in particular to a strengthening treatment process and equipment for the surface of a Gcr15 material part. Background technique [0002] Bearings are subjected to great pressure and friction during work, requiring bearing steel to have high and uniform hardness and wear resistance, as well as a high elastic limit. High-carbon chromium bearing steel GCr15 is a material containing about 1% carbon and 1.5% chromium. It is widely used in the manufacture of various bearings because of its good wear resistance, fatigue resistance and dimensional stability. It is currently the world's The world's largest production of bearing steel. [0003] The failure parts of bearing parts made of GCr15 steel are often the surface or subsurface layer, and the failure form is mostly wear or fatigue spalling. Applying modern surface analysis technology to study the microst...
