On the shear strength of laser brazed SiC–steel joints: Effects of braze metal fillers and surface patterning

Joining of Cf/C and Cf/SiC Composites to Metals

“…The best microstructures were attained for 40 at% Si alloy joints, closely agreeing with the thermodynamic model, whereas higher Si content alloys exhibited localized debonding of the brazing alloy from the SiC. The AgCuTi filler poorly wets SiC [Südmeyer et al, 2010]. Titanium and silicon carbide in the temperature range between 1250 and 1500 °C form the ternary phase Ti 3 SiC 2 [Gottselig et al, 1990] which could improve the wettability if the chemical potential is appropriate for its formation.…”

Dissimilar laser brazing of h-BN and WC-Co alloy in Ar atmosphere without evacuation process

“…The brazing process is used in many industrial fields for developing engineering structures and electronic devices [1][2][3][4][5][6][7][8][9][10][11][12][13]. This process has several advantages making it suitable for use in joining dissimilar materials and materials which are difficult to connect precisely; further, this process can be efficiently applied to the mass production of structures and devices.…”

“…Among brazing processes [16], laser brazing [10,11,13,[17][18][19][20][21][22][23][24][25][26][27][28][29][30] has good characteristics for a dissimilar joining process because of the possibility of short heating time and small heating area, and suppression of damage to the base materials without a furnace, in comparison with conventional furnace brazing.…”

Laser Brazing of a Hexagonal Boron Nitride Block to a Cemented Carbide Plate with Silver-Copper-Titanium Alloy Filler in Argon Atmosphere Including Different Oxygen Contents

“…Among different brazing processes 16) , laser brazing 10,11,13) has good characteristics for use as a dissimilar joining process in comparison with conventional furnace brazing 8,12) because of advantages such as a short heating time, small heating area, suppression of damage to the base materials, and not requiring a furnace. Therefore, we tried to develop a laser brazing process of ceramics and metals that can be carried out using simple equipment, and an easy system of controlling the atmosphere in a short heating time, without expensive equipment such as a high-vacuum system.…”

“…The brazing process is used in many industrial fields for developing engineering structures and electronic devices [1][2][3][4][5][6][7][8][9][10][11][12][13] . This process has several advantages making it suitable for use in joining dissimilar materials precisely.…”
