Titanium gold technology, which belongs to the coating technology, adds pre-plating and electroplating process steps on the basis of conventional titanium plating process. The pre-plating process is to place the activated plating part in the aqueous solution of salt and hydrochloric acid for chemical treatment; electroplating process The bath components include nickel sulfate, nickel chloride, boric acid, sodium lauryl sulfate, saccharin, and brighteners. This process has the advantages of simplicity, practicality, and good effects. The film thickness of the titanium aluminum profiles obtained by this process HV ≈ 1500, under the same conditions than the 22K gold plating wear 150 times, can be processed into various forms of gold, color, black and other bright variety of aluminum products.
Titanium-plated aluminum technology, including material selection, polishing, chemical deoiling, water rinse, activation, vacuum titanium plating process steps, is characterized in that it also includes:
a. Pre-plating process. The process consists of placing titanium aluminum profiles activated and rinsed with fresh water in a liquid consisting of salt, hydrochloric acid and water for chemical treatment. The processing temperature is room temperature, and the processing time is violent to the liquid. until;
b. Electroplating process, wherein the plating solution comprises nickel sulfate, nickel chloride, boric acid, sodium lauryl sulfate, saccharine, brightener, and the process conditions: current 3-4A/dm2 cathode movement, 5-7A/dm2 Air stirring, bath temperature 50-60°C, pH 3.9-4.2, plating time 15 minutes.
Alnico is an alloy of Aluminium, Nickel and Cobalt.It also contains Iron , Copper ,Titanium, Different metal
component constitution will form different magnet properties, application will also change accordingly.
Alnico is produced by sintered or casted technique,Its`surfaces may need machining,or to be ground for a smoother surface finish and looks brightly metallic looking. Casting means can producing AlNiCo forvariety sizes and shapes, Sintered Alnico is subsize and have very tiny tolorance but machanical performance is not good.
The most commonly used Alnico is Alnico5. There are 4 sort of cast Alnico5 plus a singlesort of sintered Alnico5 (sintered Alnico and cast Alnico have slightly different magnetic and mechanical performance). Among the permanent magnetic materials, AlNiCo have the best reversible temperature coefficient, the highest working temperature up to 500 ℃,it has the
hardest and toughest strongness.Most ALNICO Magnet grades are anisotropic (axial / vertical direction add magnetization).The others are isotropic(horizontal direction magnetized and usually have many poles on one magnet) they are weaker on magnetism but offer more options on design and properties.
