发明名称 HARD-FACING ALLOYS HAVING IMPROVED CRACK RESISTANCE
摘要 Weld deposit compositions with improved crack resistance, improved wear resistance, and improved hardness are provided by controlling matrix grain size and balancing Titanium and/or Niobium with Carbon and/or Boron content. Additionally, the presence of coarse chromium carbides is drastically decreased to reduce the amount of check-cracking. Preferably, the weld deposit is produced from a flux-cored or metal-cored wire. The weld deposit characteristics include a matrix having a fine grain size, small evenly dispersed carbides within the matrix, and a small amount of Carbon in the matrix.
