Question about induction cladding
who can tell me something about induction clading.dose it better than other process such as palama spray,lazer clading and so on.

RE: about induction cladding
Hi littlejialei

Sign0016 to the Surface Engineering Forum.

I am unclear about what induction cladding really means.

Induction heating as a post process to cure/fuse pre-placed coatings - alternative means of heating to flame, furnace, plasma, laser etc.. Induction fusing of NiCrBSi coatings.

Induction heating as a source of heat in the actual coating process - induction generated plasma - induction heating/melting of coating feed stock or induction pre-heating/post-heating during coating process - induction assisted laser cladding.

I think we need to know more information on the specific form of "induction cladding" that you are interested in before we can comment on whether it is better or not compared to other processes.

thanks very much for your apply, induction heating is not induction cladding , what i said is a process ,which the work piece is pre-coated with metal powder, then melt powder directly with induction coils.

RE: about induction cladding
Might help if we knew what configuration the work piece is ..round,flat ect.. and wht the substrate is as well as the powder type you would like to bond on , what you have described sounds like powder coating where you use static charge to attract the powder prior to the heat cycle.

RE: about induction cladding
As well as the melting temperature is criticall for this applications, and the temperature range for the fusion is very short, and change from one piece to another, so to melt the coating after spray, the best way is to do it by hand, exsept if porosity and hardness is not an important issue, in this case you can melt the coating by induction eating or using an furnace.

Best regards
Luigi

Pretty much as I said "Induction heating as a post process to cure/fuse pre-placed coatings - alternative means of heating to flame, furnace, plasma, laser etc.. Induction fusing of NiCrBSi coatings". I think I'd prefer the term induction fusing.

How do you pre-coat with metal powder? Is it applied as a slurry/paste bound with some kind of carrier, or thermally sprayed or other method?

Nature of substrate and coating - materials, shape, size, coating thickness?

Advantages of induction heating will be possibility of extremely high heating rates, precision placement of heat effected zone and the fact heat is generated internally within body of substrate and coating i.e. it does not require heat transfer via radiation, convection or conduction as used in many of the other processes. Ideal for automated high production processing of simple geometric shaped parts.

On the negative side - high investment for induction heating equipment, different inductors/induction coils will be required for different shape/size parts. High development effort/cost in design/development/testing inductors. Not suited to complex shapes.

As to the question, does it do it better than other processes? - well yes and no, lots of ifs and buts Big Grin No process is better than another generically, they will all excel in particular applications that they are suited. If you want to produce thousands of the same parts of the nature of say simple shafts with fused coatings, then induction fusing/cladding could be hard to beat.
