Spiral Lock Gear PM Sintered Part
Powder metallurgy There are many technical difficulties in the preparation of bulk amorphous materials by ordinary powder metallurgy. As a new generation of sintering technology, SPS is expected to make technological progress in this area. SPS is used to sinter amorphous Al-based powders produced by mechanical alloying to obtain bulk disc samples (10mm×2mm).

40CrNi belongs to hypoeutectoid steel, completely austenitic after heating at 860℃, and eutectoid ferrite precipitation when normalizing cooling, and then austenite transformation into pearlite type of structure (lamellae). Because of the faster cooling rate and the smaller spacing between pearlite sheets, it is easy to get sortenite or troostite structures (both of which belong to pearlite in a broad sense). So, the structure is ferrite + pearlite |

Powder metallurgy There are many technical difficulties in the preparation of bulk amorphous materials by ordinary powder metallurgy. As a new generation of sintering technology, SPS is expected to make technological progress in this area. SPS is used to sinter amorphous Al-based powders produced by mechanical alloying to obtain bulk disc samples (10mm×2mm). Magnetic amorphous alloys are produced under 375MPa. Prepared at 503K for 20 minutes, containing amorphous phase and crystalline phase and residual Sn phase. The crystallization temperature of its amorphous phase is 533K. The Mg80Ni10Y5B5 bulk amorphous alloy was prepared under the conditions of 423K and 500MPa by pulse current, and it was mainly amorphous phase after analysis. Amorphous Mg alloy has higher corrosion potential and lower corrosion current density than A291D alloy and pure magnesium, and amorphization improves the corrosion resistance of magnesium alloy.

What are the product characteristics of powder metallurgy? Powder metallurgy helical gears for automobiles
The basic process of powder metallurgy process is: the preparation of raw material powder. The existing milling methods can be roughly divided into two categories: mechanical methods and physical and chemical methods. The mechanical method can be divided into: mechanical pulverization and atomization method; physical chemical method is divided into: electrochemical corrosion method, reduction method, chemical method, reduction-chemical method, vapor deposition method, liquid deposition method and electrolytic method. Among them, the most common applications are reduction method, atomization method and electrolysis method. The powder is formed into compacts of the desired shape. The purpose of forming is to make a compact of a certain shape and size, and to make it have a certain density and strength. The molding method is basically divided into pressure molding and non-pressure molding. Compression molding is mostly used in compression molding. Powder metallurgy helical gears for automobiles
