Process for preparing modified pigments

Abstract: A process for preparing a modified pigment having attached at least one organic group is described. This process comprises the step of combining, in any order, a colored pigment, an aromatic amine, a base, and an aqueous medium to form a mixture, and then combining the mixture and a diazotizing agent to form the modified pigment. The aromatic amine comprises at least two carboxylic acid groups, preferably being vicinal. The resulting modified colored pigment can be used in an inkjet ink composition to produce printed images having good overall properties.

Corrosion resistant nickel-iron alloy

Abstract: Disclosed is an alloy eminently suited for use as a tubular product in deep, sour gas operations. The alloy has an optimum combination of corrosion resistance, high strength in the cold worked condition and resistance to sulfide stress cracking and stress corrosion cracking. A typical alloy contains, in weight percent, 0.03 carbon, 22 chromium, 36 iron, 3 molybdenum, 1 manganese, 36 nickel, 0.60 silicon, 0.15 nitrogen, up to 3 tungsten and incidental impurities including copper, cobalt, columbium, tantalum and titanium.

Wear-resistant power metallurgy nickel-base alloy

Abstract: A wear- and abrasion-resistant article of sintered metal powder consists of chromium from about 23 percent to about 29 percent, tungsten from about 8 percent to about 15 percent, cobalt from about 8 percent to about 15 percent, molybdenum from about 8 percent to about 15 percent, carbon from about 1.65 percent to about 5 percent, boron up to about 1 percent, manganese up to about 1.3 percent, silicon up to about 1.3 percent, iron from about 10 percent to about 17.5 percent, and the balance nickel in amount at least about 20 percent and incidental impurities.
